- Removed some GCC warnings.

- Fixed: MinGW doesn't have _get_pgmptr(), so it couldn't compile i_main.cpp.
- Fixed: MOD_WAVETABLE and MOD_SWSYNTH are not defined by w32api, so MinGW
  failed compiling the new MIDI code.
- Fixed: LocalSndInfo and LocalSndSeq in S_Start() need to be const char
  pointers, since "" is a constant.
- Fixed: parsecontext.h was missing a newline at the end of the file.
