# Cross-compile from Linux to Win32 using mingw32 cross-compiler as
# provided by Debian.  For Ogg and MP3 support, you need to compile
# those libraries separately and put them in libs/.  If the libraries
# are absent, sbagen is compiled without Ogg/MP3 support.
#
# Compiling these libraries is not the easiest thing to do, and doing
# it the way I did it requires a MinGW and MSYS setup running on
# Windows (or under emulation), under which you can use the
# 'mk-libmad-mingw' and 'mk-tremor-mingw' scripts to build the
# libraries in a rather improvised manner.  You only have to do this
# once, after which you can copy them to libs/ and rebuild endlessly
# on Linux without trouble.
