[Tinycc-devel] Patch to allow linking PIC-objects into static executable

[tike64]

Hi,

Attached patch makes it possible to use PIC-objects, i.e. objects with
a GOT, in a non-dynamic executable. It is against latest cvs patched
with Daniel's gotoff32 patch:

http://lists.gnu.org/archive/html/tinycc-devel/2006-12/msg00016.html

Maybe someone could verify it and apply to cvs
