There is now v2 which uses cc-option-add

Thats what the URL says. Unclear what the connection between -fpic and -fPIE
(?) is.

Yes, 4.1.2 works as well.

According to the PDF manuals at https://gcc.gnu.org/onlinedocs/ a
"-fno-foo" is mentioned, so I think -fno-pic is recognized. I will see
if I find a copy of SLE10 to verify with 4.1.2.

We support >=4.1. Please check those as well.

In my testing gcc-4.3 and 4.5 know about this option.

If the default compiler silently defaults to to -fPIC/-fPIE building
rombios fails:
ld -melf_i386 -s -r 32bitbios.o tcgbios/tcgbiosext.o util.o pmm.o -o
32bitbios_all.o
There are undefined symbols in the BIOS:
