#-fpmath=xx is reported to cause trouble on pentium4 m series
#(for 3.0.x: this sort of thing should be handled by the --enable-sse
#style configure flags. these are set below using the use variables,
#but under gcc-3.2.x, sse2 seems to cause trouble.)

# in gcc 3.2.3 at least, using sse or sse2 causes trouble with -O3
# according to the docs, -O0 can cause trouble too! So pending further
