Hello parisc-linux hackers,

Finally tracked down the glibc problem (with help from tausq and others
:)).  I have attached the changelog entry, and the dpatch.  I am
assuming you will push it upstream Carlos?


When working on this problem it caused a gcc ICE.  The gcc ICE has been
reported at:


http://gcc.gnu.org/cgi-bin/gnatsweb.pl?cmd=view%20audit-trail&database=gcc&pr=10215

This is why the ENTRY_POINT macro is uglier than really necessary.

Once this patch is in glibc, then we can remove the RGH_FIX hack
from the 2.4 kernels as well.

oh.  This patch fixes this assert in glibc:

rbrad@vega:~$ /lib/ld.so.1 --verify /bin/sh
Inconsistency detected by ld.so: rtld.c: 879: dl_main: Assertion
`_rtld_local._dl_rtld_map.l_libname' failed!

Thanks!

- Ryan
