# 20220318 bkw: Modified by SlackBuilds.org, BUILD=3: fix build on 15.0.
# Actually it was *building* OK, but would segfault on startup.
# - add gcc5 as a dep, use it for the build.
# - build without fluidsynth, 15.0's is too new for this old code.
#   looks like there's still OPL emulation for MIDI.
# - build without svgalib, 15.0's is too old. I haven't seen svgalib
#   do anything but crash and lock up the console any time I've tried
#   it in the last 20 years or so, anyway.

# Note to self: there's a smorgasboard of patches here:
# https://gitweb.gentoo.org/repo/gentoo.git/tree/app-emulation/dosemu/files
# ...none of which fix the segfaults or the fluidsynth issues.

# Included in Slint by Didier Spaier ddidieratslintdotfr
