--- Comment #25 from Sergey <fukanchik at gmail dot com> --- Sorry. I mean i am getting the following error: > "../../gcc-4.5/libcpp/files.c", line 1193: Error: Cannot assign char* to int. this is obstack related stuff. The following does not compile: obstack_free (&pfile->nonexistent_file_ob, 0); modifying it this way: obstack_free (&pfile->nonexistent_file_ob, (void*)0); helps with compilation. Also happens in symtab.c, init.c, identifiers.c. And yes, i'm building cpp & disable bootstrap if that counts.
