Greg Ward | f34506a | 2000-06-29 22:57:55 +0000 | [diff] [blame] | 3 | Provides the CygwinCCompiler class, a subclass of UnixCCompiler that |
| 4 | handles the Cygwin port of the GNU C compiler to Windows. It also contains |
| 5 | the Mingw32CCompiler class which handles the mingw32 port of GCC (same as |
| 6 | cygwin in no-cygwin mode). |
