# gcc-4.0.x used to cause bad hexen2 binaries when unit-at-a-time mode is active:
# crusader's tomed ice mace causes segmentation fault. the bug showed up after the
# cmd layer synchronization between hexen2 and hexenworld trees, and it now seems
# to be fixed (actually worked-around by not pointing to static buffers and using
# dynamic allocation).
#
# this script is here to detect gcc-4.0 versions. on the other hand, 3.3.x, 3.4.x,
# 4.1.x and 4.2 versions seem to produce good binaries.
