# -O2 are enough optimizations.

# -fno-strict-aliasing since the source doesn't comply
#  with strict aliasing rules and it's next to impossible
#  to get it there...
#
# -fomit-frame-pointer since the framepointer is mostly
#  useless for debugging Quake II and slows things down.
#
# -g to build allways with debug symbols. Please do not
#  change this, since it's our only chance to debug this
#  crap when random crashes happen!
#
# -fPIC for position independend code.
#
# -MMD to generate header dependencies.
