 Hi,

I have tested -fno-threadsafe-statics now and it does not affect so much,
IMHO:

$ c++  -I../include  -time -O0 -Wall   -DPIC -fPIC  -c ir.cc -o ir.pic.o
# cc1plus 68.57 2.26
# as 5.92 0.27

$ c++  -I../include  -fno-threadsafe-statics -time -O0 -Wall   -DPIC -fPIC  -c ir.cc -o ir.pic.o
# cc1plus 67.94 2.04
# as 5.86 0.26

Cheers,
Karel
