../configure CXXFLAGS="-march=i686" ...

works fine, thanks

mandriva 2009.0, gcc 4.3.2

errors:

trying

../configure CFLAGS="-march=i686" ACE_CFLAGS="-march=i686"

but dont work

make simple test:

# cat test.c
int main()
{
   int i = 3;
   int j = __sync_add_and_fetch(&i, 1);
   return 0;
}

# gcc test.c
/tmp/cccOSsgM.o: In function `main':
test.c:(.text+0x27): undefined reference to `__sync_add_and_fetch_4'
collect2: выполнение ld завершилось с кодом возврата 1
#

# gcc -march=i686 test.c
#

as you see with -march=i686 should works. how get it in mangos configure?
