"""distutils.cygwinccompiler

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 an import library for its dll
#      - create a def-file for python??.dll
#      - create an 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.
