Comment 2 Jeffrey Moyer 2004-03-22 14:58:12 EST

I've taken your patch and ported it to the 4.1.1 code base.  In order
to push this upstream, I'd have to have some test to see whether the
compiler supports pie.  What is the best way to do so?

Comment 3 Ulrich Drepper 2004-03-22 16:03:12 EST

I don't have an old compiler at hand but running a simple compile test
in gcc with -fpie -pie on the command line shoud do.

Write a configure test which temporarily adds -fpie to CFLAGS and -pie
to LDFLAGS and then compile and link a dummy program.   Should be
perhaps 10 lines of autoconf code.
