[Slackbuilds-users] Modifying config.mk's CFLAGS variable

[Tim Dickson]

for longer term solution submit a patch upstream. you might want to 
check the optimization flag because some applications don't run 
well/have runtime issues with some flags. In those cases you don't want 
to override them. (I have at least one package with that issue.)
