>Organization:
>Environment:
sparc-sun-solaris2.8
>Description:
Compiling gcc 3.2 on a newly installed Solaris 8 machine with the following two commands

 % ../gcc-3.2/configure --prefix=/prj/pack/gcc-3.2 --with-as=/usr/ccs/bin/as --with-ld=/usr/ccs/bin/ld --disable-nls --enable-languages=c,c++
 % make bootstrap

The last step fails with the following

./xgcc -B./ -B/prj/pack/gcc-3.2/sparc-sun-solaris2.8/bin/ -isystem /prj/pack/gcc-3.2/sparc-sun-solaris2.8/include -isystem /prj/pack/gcc-3.2/sparc-sun-solaris2.8/sys-include -O2  -DIN_GCC    -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -isystem ./include  -fPIC -g -DHAVE_GTHR_DEFAULT -DIN_LIBGCC2 -D__GCC_FLOAT_NOT_NEEDED  -I. -I. -I../../gcc-3.2/gcc -I../../gcc-3.2/gcc/. -I../../gcc-3.2/gcc/config -I../../gcc-3.2/gcc/../include -fexceptions -c ../../gcc-3.2/gcc/unwind-dw2.c -o libgcc/./unwind-dw2.o
