Known problems when compiling FB

Win32 rtlib compilation error: wchar.h: unknown type name 'dev_t'

   http://sourceforge.net/p/mingw/bugs/2039/

   The wchar.h header file from MinGW.org contains a struct _stat64 
   declaration that does not compile when _NO_OLDNAMES is defined, because 
   it uses dev_t, ino_t, mode_t which are only available with an _ 
   underscore prefix (_dev_t etc.) under _NO_OLDNAMES. For the FB rtlib we 
   #define _NO_OLDNAMES when compiling.

   To work around this issue, adjust wchar.h and add _ underscore prefixes 
   to those typedef names in the struct _stat64 declaration.

Win32 rtlib compilation error: _controlfp, _PC_64 undeclared

   CC src/rtlib/obj/hinit.o
   src/rtlib/win32/hinit.c: In Function 'fb_hInit':
   src/rtlib/win32/hinit.c:21:5: warning: implicit declaration of Function '_controlfp' [-Wimplicit-function-declaration]
   src/rtlib/win32/hinit.c:21:17: Error: '_PC_64' undeclared (first use in this function)

Both the MinGW.org runtime and GCC have a float.h header, and in some 
setups the GCC one is found before the MinGW one, causing the above errors.

Easiest temporary fix: Append #include_next <float.h> to gcc's float.h (
C:\MinGW\lib\gcc\[target]\[version]\include\float.h)

MinGW binutils ld versions 2.18 to 2.21

   fbc triggers a bug (binutils ld bug 12614) in the mentioned linker 
   versions causing it to produce broken binaries in some cases. It's fixed 
   in binutils 2.21.1 and up.

MinGW.org runtime's globbing code changes case of command line arguments

   http://sourceforge.net/p/mingw/bugs/2062/

   MinGW.org's runtime (mingwrt-4.0.3) changed the case of command line 
   arguments given to the program. If the argument matched an existing 
   file/directory name and only differed in case, it was adjusted to match 
   the exact spelling. This can cause problems with programs whose command 
   line parsing is not case-insensitive. For example, gui became Gui if 
   there was a directory called Gui. This affected fbc.exe's -s gui option, 
   making it impossible to use, as fbc.exe refused to accept -s Gui.

-lXpm not found on Debian x86_64

   The ia32-libs-dev package (for example on Debian 6) for some reason does 
   not contain a /usr/lib32/libXpm.so symlink, even though it does contain 
   those for the other X11 development libraries. This apparently can be 
   fixed by creating the symlink manually:

   ln -s /usr/lib32/libXpm.so.4 /usr/lib32/libXpm.so

DJGPP: Too many open files

   If a DJGPP program fails with a too many open files error on Windows, 
   try the following to increase the number of available file handles:

      * Use msconfig to add PerVMFiles=255 to the [386Enh] section of 
        SYSTEM.INI
      * Edit the files= setting in C:\WINDOWS\system32\CONFIG.NT: 
        files=255
      * Also see http://www.delorie.com/djgpp/v2faq/faq9_7.html
