gcc 2.95.2 failes to compile

["David C. M. Bilsby" <bilsby at signal dot dera dot gov dot uk>]

Hi,
	I am having problems compiling the gcc-2.95.2 distribution on a SUN 
UltraSPARC Solaris 2.6 system.
	
	I obtained the source and extracted it into /opt/src/gnu/gcc-2.95.2. I 
then proceeded to configure the source, and as suggested did so from a different 
object directory. The configuration was as follows:
	
% gzcat gcc-2.95.2.tar.gx | tar -xvf -
% mkdir gcc-object
% cd gcc-object
% ../gcc-2.95.2/configure --prefix=/opt/gnu --with-cpu=ultrasparc --enable-haifa
% gmake bootstrap MAKE=gmake

	During configuration, a previous installation of gcc (2.8.1) was 
detected and used for the first stage compiler. I have however tried the SUN 
v4.2 compiler with no success. 
	
	An initial problem encountered was that the make stopped claiming it 
could not find fixinc.sh. 
	
TARGET_MACHINE=sparc-sun-solaris2.6; srcdir=`cd ../../gcc-2.95.2/gcc; pwd`; \
INSTALL_ASSERT_H=install-assert-h; SHELL=/bin/sh ;\
export TARGET_MACHINE srcdir INSTALL_ASSERT_H SHELL ; \
/bin/sh ./fixinc.sh `pwd`/include /usr/include 
./fixinc.sh: ./fixinc.sh: cannot open
gmake[2]: *** [stmp-fixinc] Error 1
gmake[2]: Leaving directory `/opt/src/gnu/gcc-object/gcc'
gmake[1]: *** [bootstrap] Error 2
gmake[1]: Leaving directory `/opt/src/gnu/gcc-object/gcc'
gmake: *** [bootstrap] Error 2

	I solved this by copying the ../gcc-2.95.2/gcc/fixinc.sh to 
gcc-object/gcc/fixinc.sh.
	
	This fixed the compilation continued OK ultil it tried to execute 
gengenrtl which failed with a segmentation fault.
