It stops various tests working - eg, the asm tests for ssh, and various assembler tests for GNU binutils (from memory). As a complete solution, this lacks a certain something :)
This is because of another bug in gcc 2.7.x: -pipe applied to a .s file will hang the compiler. The compiler driver incorrectly assumes that when -pipe is in use, there's something ahead of the assembler in the pipeline. Applying this patch to /.../gcc-lib/MACHINE/VERSION/specs will fix it: =cut here= --- specs~ Wed Jun 26 15:14:20 1996 +++ specs Sun Jan 18 13:46:30 1998 @@ -4,3 +4,3 @@ *asm_final: -%{pipe:-} +%| =cut here= and if anyone cares, I have autoconf macros to detect the bug and hack around it. The bug is fixed in egcs and I hope also in 2.8. zw
