# This script shows how to generate a 64 bit version of cyglsa.dll.
# The 32 bit version will not work on 64 bit systems.
#
# Note that you need MinGW-w64 GCC, headers, and import libs.  On Cygwin,
# the required packages are: mingw64-x86_64-binutils, mingw64-x86_64-gcc-core,
# mingw64-x86_64-headers, and mingw64-x86_64-runtime.
#
# Note that this is for building inside the source dir as not to interfere
# with the "official" 32 bit build in the build directory.
#
# Install the dll into /bin and use the cyglsa-config script to register it.
# Don't forget to reboot afterwards.
#
# Add "-DDEBUGGING" to CFLAGS below to create debugging output to
# C:\cyglsa.dbgout at runtime.
