$gcc (GCC) 4.4.0 20081213 (experimental)
$echo $CFLAGS
$-pipe -O3 -march=core2 -mfpmath=sse -ftree-vectorize
-ftree-parallelize-loops=2 -pthread -fopenmp
I compiled and installed gmp,mpfr with this cflags, after that, I try to
compile gcc
trunk and got :
gcc -g -fkeep-inline-functions -DIN_GCC -W -Wall -Wwrite-strings
-Wstrict-prototypes -Wmissing-prototypes -Wcast-qual -Wold-style-definition
