Hey guys.
Here's the lowdown:  I run Windows XP with SP2.  I downloaded the 19th nightly build of Code::Blocks for this month.  I downloaded and installed MinGW and everything that is associated with it, according to the OdaWiki.  Extracted everything into C:\MinGW, including the "include" and "lib" folders for the SDL 1.2.11 and SDL_mixer 1.2.11 files.  I received the latest files from the SVN and put them in a directory.  The OdaWiki states to open Code::Blocks and rebuild the entire workspace, so that is what I did; I attempted to rebuild the workspace that was in the SVN.  Herein lies the problem:  it will compile quite a few files before giving me a warning that says 
"Warning: .drectve `/DEFAULTLIB:"MSVCRT" /DEFAULTLIB:"OLDNAMES" ' unrecognized", 
and three errors that say, 
"1)C:\MinGW\lib\SDLmain.lib(./Release/SDL_win32_main.obj):C:\SDL-1.2.11\Src\:(.text[_main]+0x55): undefined reference to `_alloca_probe'
2)C:\MinGW\lib\SDLmain.lib(./Release/SDL_win32_main.obj):C:\SDL-1.2.11\Src\:(.text[_WinMain@16]+0x181): undefined reference to `_alloca_probe'
3)C:\MinGW\lib\SDLmain.lib(./Release/SDL_win32_main.obj):C:\SDL-1.2.11\Src\:(.text[_WinMain@16]+0x1c1): undefined reference to `_alloca_probe' ".  
I am confused as to what this means; I had thought that merely putting all of the necessary SDL files into the MinGW directory would have sufficed.  I googled "sdl codeblocks" and came to a page that said how to install SDL for use with Code::Blocks, so I followed those instructions to see if I could finally link everything.  No go; same warning and errors.
It would be totally tubular if I could get this project compiling so I could play around with it and maybe, hopefully, provide some patch fixes after I've looked into it.  If anyone has any idea what I might be doing wrong, or not doing at all, please shed some light on my situation [sad face].  
Oh, here's a screen shot of what happened in case I confused anyone.  Thank you for any help in advance.  I'll try to catch someone in #odamex when I get the chance.
