+# 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.
