# 20220215 bkw: Modified by SlackBuilds.org:
# - added -j1 to the make commands. parallel builds are broken. they
#   may occasionally work, but it's unreliable.
# Note: there are other issues with this script:
# ! SLKCFLAGS are never used.
# ! -Werror is included in the flags that do get used, meaning this
#   will break in the future when Slackware's gcc gets upgraded.
