#
# Makefile to build XZ Utils using MinGW
#
# Make flags to alter compilation:
#
#   DEBUG=1     Enable assertions. Don't use this for production builds!
#               You may also want to set CFLAGS="-g -O0" to disable
#               optimizations.
#
#   W64=1       Build for 64-bit Windows. Make sure that you have 64-bit
#               MinGW in PATH.
#
#   WINE=1      Shortcut to set CC, AR, and STRIP to use Wine to run Windows
#               versions of MinGW binaries.
#
# The usual CPPFLAGS and CFLAGS are supported too.
