# BeOS gccs (geekgadgets + 2.95.3) have this old bug: 
# after this:          const wchar_t x[] = L"foo";
# x[2] is "optimized" into: (wchar_t)((char *)x)[2] (== 0)
#
# see also: http://gcc.gnu.org/ml/gcc-patches/2000-09/msg00454.html
#
# Unfortunately this behavior isn't controlled by a flag so we can't
# use any O optimizations at all. (the behavior kicks in at -O1)

# Optimizations aren't currently defined in the mh files.
# So Don't override any flags set by the user or runConfigureICU.
