+
+Provides the CygwinCCompiler class, a subclass of UnixCCompiler that
+handles the Cygwin port of the GNU C compiler to Windows. It also contains
+the Mingw32CCompiler class which handles the mingw32 port of GCC (same as
+cygwin in no-cygwin mode).
+"""
+
+# problems:
+#
+# * if you use a msvc compiled python version (1.5.2)
+# 1. you have to insert a __GNUC__ section in its config.h
+# 2. you have to generate a import library for its dll
+# - create a def-file for python??.dll
+# - create a import library using
+# dlltool --dllname python15.dll --def python15.def \
+# --output-lib libpython15.a
+#
+# see also http://starship.python.net/crew/kernr/mingw32/Notes.html
+#
+# * We put export_symbols in a def-file, and don't use
+# --export-all-symbols because it doesn't worked reliable in some
+# tested configurations. And because other windows compilers also
+# need their symbols specified this no serious problem.
+#
+# tested configurations:
+#
+# * cygwin gcc 2.91.57/ld 2.9.4/dllwrap 0.2.4 works
+# (after patching python's config.h and for C++ some other include files)
+# see also http://starship.python.net/crew/kernr/mingw32/Notes.html
+# * mingw32 gcc 2.95.2/ld 2.9.4/dllwrap 0.2.4 works
+# (ld doesn't support -shared, so we use dllwrap)
+# * cygwin gcc 2.95.2/ld 2.10.90/dllwrap 2.10.90 works now
+# - its dllwrap doesn't work, there is a bug in binutils 2.10.90
+# see also http://sources.redhat.com/ml/cygwin/2000-06/msg01274.html
+# - using gcc -mdll instead dllwrap doesn't work without -static because
+# it tries to link against dlls instead their import libraries. (If
+# it finds the dll first.)
+# By specifying -static we force ld to link against the import libraries,
+# this is windows standard and there are normally not the necessary symbols
+# in the dlls.
+# *** only the version of June 2000 shows these problems
+# * cygwin gcc 3.2/ld 2.13.90 works
+# (ld supports -shared)
+# * mingw gcc 3.2/ld 2.13 works
+# (ld supports -shared)
+
+# This module should be kept compatible with Python 2.1.
