compiler build fails on solaris 2.6

[Francois Ostiguy <ostiguy at fnal dot gov>]

Hi,

Your work in putting  together this release of GNU gcc are
immensely appreciated. I would nevertheless like to report the following
bug:
  
Description:

The program gengenrtl core dumps when I use gcc-2.8.1 to build the 
1st stage compiler. I tried using egcs 1.1.2 instead of gcc-2.8.1; 
this seems to work, however, when gengenrtl is compiled using the 
stage1 gcc-2.95, the executable core dumps again. I tried compiling *just*
gengenrtl with egcs-1.1.2 at every pass. In that case, I get a little bit
further along, but the 1st stage  compiler eventually dies with an
internal error ...

Best Regards and Thanks !

-Francois
