# Build a binary package on Windows with MinGW and MSYS
#
# Set the paths where MinGW, Mingw-w32, or MinGW-w64 are installed. If both
# MinGW and MinGW-w32 are specified, MinGW-w32 will be used. If there is no
# 32-bit or 64-bit compiler at all, it is simply skipped.
#
# Optionally, 7-Zip is used to create the final .zip and .7z packages.
# If you have installed it in the default directory, this script should
# find it automatically. Otherwise adjust the path manually.
#
# If you want to use a cross-compiler e.g. on GNU/Linux, this script won't
# work out of the box. You need to omit "make check" commands and replace
# u2d with some other tool to convert newlines from LF to CR+LF. You will
# also need to pass the --host option to configure.
