>Description:
Segmentation fault in gnat compiling ada.ads in stage 2.
The problem is caused by not specify "-mdisable-indexing"
when building the C files comprising the ada compiling.

The build configuration was changed last October by
this patch:

2001-10-08  Zack Weinberg  <zack@codesourcery.com>

        * aclocal.m4 (gcc_AC_PROG_GNAT): New.
        * configure.in: Use it.
        * configure: Regenerated.
        * config/pa/t-linux, config/pa/t-pa, config/pa/t-pa64,
        config/pa/t-pro: Set T_ADAFLAGS, not ADA_CFLAGS.

ADA_CFLAGS is used in building both c and ada files in the
ada compiler.  T_ADAFLAGS is only used when compiling ada
files.  The above option needs to be specified for both
c and ada files for correct operation of gnat.

A further problem is that T_ADAFLAGS is a target configuration
flag.  The "-mdisable-indexing" option needs to be specified
for the host not the target.  This was observed recently
when a cross compiler was used to port ada to hppa-linux.

The PR has been marked high-priority because it is a
regression.
