# this is necessary for reproducible builds (see: https://wiki.debian.org/ReproducibleBuilds/TimestampsInPEBinaries for additional information)

# note: the above documentation also references an ability to set an optional timestamp - this behaviour seems to no longer be supported in more recent versions of mingw32-gcc (the help docs no longer reference that functionality)
|

# these flags have to be passed through to the underlying gcc process using the -extldflags option in the underlying go linker, note that the whole flag is quoted...this is necessary.
