[Fwd: Re: sigpending.c causes libc build to fail]

[Dzung Nguyen <dunguyen at iol dot unh dot edu>]

Hi.  The following is the original error message when we built libc with 
bootstrap-gcc_3.2 on our alphaev56 machine.  
I have received help indicating there may be a bug with the compiler 
that caused the problem. Anybody could help me out?  
Thanks.

I think that must be a compiler bug.  I haven't been able to try an alpha
build myself lately, but I think they have been tested with the
gcc-3_2-rhl8-branch compiler.  I can't see anything wrong with the asm
there (which is the INLINE_SYSCALL macro variant for 2-arg syscalls).
