1# We need to use -fPIC when we are using gcc to compile the routines in
2# crtstuff.c. This is only really needed when we are going to use gcc/g++
3# to produce a shared library, but since we don't know ahead of time when
4# we will be doing that, we just always use -fPIC when compiling the
5# routines in crtstuff.c. Likewise for libgcc2.c. This is less painful
6# than multilibbing everything with PIC and PIC-not variants.

8# The pushl in CTOR initialization interferes with frame pointer elimination.

| 1# We multilib libgcc for -fPIC, to get real PIC code in it.
2# NOTE: We must use -fPIC on crt{begi,end}.o else we get an RTLD error
3# "cant set protections on segment of length blah at 0x8048000".
