# Create Windows release.
# Assumes a correctly installed glib (with pkgconfig script)
# and static linking of all dependant libraries (no DLLs are
# added to the zip).
# If a win32.teco_ini exists, it is added to the release
# instead of sample.teco_ini.
# This also adds gspawn-win32-helper-console.exe to the archive
# which is required by the glib spawn functions.
# If we ever build a non-console version on Windows,
# we should include gspawn-win32-helper.exe instead.
#
# When linking in PDCurses/win32a statically, the
# environment variable PDCURSES_LIBS should be set to
