-"""distutils.cygwinccompiler\r
-\r
-Provides the CygwinCCompiler class, a subclass of UnixCCompiler that\r
-handles the Cygwin port of the GNU C compiler to Windows. It also contains\r
-the Mingw32CCompiler class which handles the mingw32 port of GCC (same as\r
-cygwin in no-cygwin mode).\r

-# problems:\r
-#\r
-# * if you use a msvc compiled python version (1.5.2)\r
-# 1. you have to insert a __GNUC__ section in its config.h\r
-# 2. you have to generate a import library for its dll\r
-# - create a def-file for python??.dll\r
-# - create a import library using\r
-# dlltool --dllname python15.dll --def python15.def \\r
-# --output-lib libpython15.a\r
-#\r
-# see also http://starship.python.net/crew/kernr/mingw32/Notes.html\r
-#\r
-# * We put export_symbols in a def-file, and don't use\r
-# --export-all-symbols because it doesn't worked reliable in some\r
-# tested configurations. And because other windows compilers also\r
-# need their symbols specified this no serious problem.\r
-#\r
-# tested configurations:\r
-#\r
-# * cygwin gcc 2.91.57/ld 2.9.4/dllwrap 0.2.4 works\r
-# (after patching python's config.h and for C++ some other include files)\r
-# see also http://starship.python.net/crew/kernr/mingw32/Notes.html\r
-# * mingw32 gcc 2.95.2/ld 2.9.4/dllwrap 0.2.4 works\r
-# (ld doesn't support -shared, so we use dllwrap)\r
-# * cygwin gcc 2.95.2/ld 2.10.90/dllwrap 2.10.90 works now\r
-# - its dllwrap doesn't work, there is a bug in binutils 2.10.90\r
-# see also http://sources.redhat.com/ml/cygwin/2000-06/msg01274.html\r
-# - using gcc -mdll instead dllwrap doesn't work without -static because\r
-# it tries to link against dlls instead their import libraries. (If\r
-# it finds the dll first.)\r
-# By specifying -static we force ld to link against the import libraries,\r
-# this is windows standard and there are normally not the necessary symbols\r
-# in the dlls.\r
-# *** only the version of June 2000 shows these problems\r
-# * cygwin gcc 3.2/ld 2.13.90 works\r
-# (ld supports -shared)\r
-# * mingw gcc 3.2/ld 2.13 works\r
-# (ld supports -shared)\r
-\r
-# This module should be kept compatible with Python 2.1.\r
