linking problem with C

Story

Recently I've got errors during building project (at linking step), spent a lot of time to solve it - wrote some perl script for solving my problem, but finally found simple and nice solution.
The problem occured when several .lib files stored the same symbol - Visual Studio in this case generates next message:
    1>Win32_Interop.lib(Win32_FDAPI.obj) : error LNK2005: socket already defined in ws2_32.lib(WS2_32.dll)
that means:
    - library file Win32_Interop.lib contains symbol 'socket'
    - library file ws2_32.lib contains symbol 'socket'
and linker can't decide which instance must be connected when somewhere called socket().

Examples of such errors (which I met):
    - yara defines symbols (strlcpy,strlcat) which is also defined in mysqlclient.lib
    - redis defines symbols (pthread_create, pthread_cond_init, pthread_cond_destroy, pthread_cond_wait, pthread_cond_signal) which is also defined in mysqlclient.lib
    - redis defines symbols (socket, WSASend, WSARecv, WSACleanup, ioctlsocket, setsockopt, getsockopt, connect, listen, bind, shutdown, htons, htonl, getpeername, getsockname, ntohs, select, ntohl, freeaddrinfo, getaddrinfo, WSASetLastError, WSAGetLastError, WSAIoctl) which is also defined in standard windows library ws2_32.lib

There are simple way - say to linker smthng like "choose them in random way":
'properties -> Linker -> General -> Force File Output' with any of next values:
    "Enabled (/FORCE)"
    "Multiply Defined Symbol Only (/FORCE:MULTIPLE)"
but it can lead to some mystic bugs. So, I don't like that way.

Here are facts which obviously lead to solution:
    - All such disambiguated symbols which I saw - it's only for internal usage in libraries. No one such symbol designed for calling outside.
    - And all such symbols I saw - was defined in one file, and called from another - so, I couldn't just make them 'static'.
    - All these projects I'm building from source code.
And here are obvious solution - if it's internal library stuff - who cares which names these internal symbols have.

So, task became 'replace all instances of lexem in projects to another lexem'.
It's refactoring task - and seems I can use typical refactoring tools. but here are things:
    - paid software (klocwork, Slickedit) - I need to use it only once to create lib file. I don't want to pay for that. And trial sucks.
    - some plugins for some IDE (Eclipse CDT, Xrefactory for Emacs, Netbeans, Qt Creator) - I don't think they have batch mode. I don't want manually click for refactoring. And I don't want install some huge ide.
    - GCC MELT - maybe, but I don't want gcc.
Actually one tool looked nice - cscope - but on the first meeting it looked creepy. And I still didn't find out how it works.

I searched ways to solve it by myself.
Simple s/lexem_A/lexem_B/ obviously won't work because if you want replace WSACleanup in redis to any another lexem - it ruins next constructions:
    auto f_WSACleanup = dllfunctor_stdcall<int>("ws2_32.dll", "WSACleanup");
because string constant will be replaced also.
Also if lexem_A is substring of some another lexem - it also will be affected.

Make lexical analysis is difficult. Especially if you are newbie in this area.

On that time I wrote perl script, which uses some simple heuristic analysis of context. Tested it on 2 projects - it worked fine. But here are simple & nice solution.

Simple and nice solution

Answet is preprocessing.
C/C++ compiler apply defines to lexems - it won't affect on substrings of another lexems; it won't affect on string constants. Ideal solution.
Even more - Visual Studio allows set defines without modifications of any source code. And even more - Visual Studio allows you do it with several projects in time! You can set defines for all projects in solution.
Just select c/c++ projects by clicking on projects with pressed 'ctrl' button (if you select also c# project, for example - nothing will work. Only c/c++ projects must be selected).
Then click right mouse button and go to
    "Properties" -> "Configuration Properties" -> "C/C++" -> "Preprocessor" -> "Preprocessor Definitions"
and add what do you want to replace in format lexemA=lexemB. For example - here are my stuff for yara (to not conflict with mysqlclient.lib):
strlcpy=libyara_internal_strlcpy
strlcat=libyara_internal_strlcat

That's it. Apply it & compile - all lexems will be replaced.

Script

Just put it here: https://github.com/HostageBrain/my_lovely_refactor
It analyzes context and replaces lexems which you needed.
Usage:
    - you are specifying extensions
    - you are specifying lexems for replacing
    - you can optional add custom data types for heuristic (redis required 2 such items)
    - you are running 'my_lovely_refactor.pl path_to_directory'
And it prints files where replacings happened. Original file saved in .N.bak extension, where N - nearest free number.
