Patch [gcc-2_95-branch]: Add missing parameter in i386.md (was: Re: BUG: Creating shared C++ libs using -march=pentiumpro broken on the release branch)

[Manfred Hollstein]

Hi there,

the  behaviour described in  my  earlier bug  report  is  caused by  a
missing     paramter   to  the    call    of   `load_pic_register'  in
exception_receiver. Fixed by the patch below.

OK to install?

Cheers, manfred
