- borland c++ 5.5.1 (no longer available, *bc*)
- DJGPP (gp.cmd,older gp.bat,*gp*)
- mingw and mingw-w64 compilers (install-compilers.cmd, zap*, *gw2*)
- mingw-w64 vityan compiler batch files for ubuntu natty and freebsd (*gwix*) are packaged with set just above. currently, you still have to specify exe or dll even there is no extension of linux binaries.
