# Win32 Makefile for Python interface to GDChart.
#
# This makefile assumes that you have the mingw32 tools installed.  Also see
# the README.
#
# Change the following as appropriate:
#
# HAVE_JPEG   Set to 0 to disable JPEG support.
# PY_INC      Include path for Python headers.
# PY_LIBPATH  Lib path for Python import library for mingw32.
# PY_LIB      Python import library.
# PNG         Path to libpng src/lib.
# ZLIB        Path to zlib src/lib.
# JPEG        Path to jpeg-6b src/lib.
# GCC         The C compiler.  Must be some flavor of gcc.
# CFLAGS      Compiler options.
# SO          Extension for shared lib.
