Re: cannot build gcc 3.2.3 in Suse 10.3 (gcc 4.2.1)

["Matteo Rama" <matteo dot rama at gmail dot com>]

thanks for the reply. It looks like replacing line 662 of read-rtl.c with
obstack_ptr_grow (&vector_stack, read_rtx (infile));
doesn't fix the problem. The error is still there:
...
../../gcc-3.2.3/gcc/read-rtl.c: In function 'read_rtx':
../../gcc-3.2.3/gcc/read-rtl.c:662: error: lvalue required as increment operand
../../gcc-3.2.3/gcc/read-rtl.c:662:60: warning: C++ style comments are
not allowed in ISO C90
../../gcc-3.2.3/gcc/read-rtl.c:662:60: warning: (this will be reported
only once per input file)
make[1]: *** [read-rtl.o] Error 1
make[1]: Leaving directory `/root/gcc/obj/gcc'
make: *** [all-gcc] Error 2

regards,
  Matteo
