The inline assembly code that caused your build
to fail was a patch that [e-mail] submitted
(see bug 151709 comment 1).

falk, could you help me with this bug report?  I
don't have a Linux alpha machine.

mach1, please provide the version info of gcc
and as on your system.  (Try "gcc -v" and "as -V".)

The syntax for the asm constraints was apparently only introduced in gcc 3.1.
This could be circumvented ad the cost of decreased readability. However,
IIRC gccs that old miscompiled mozilla anyway, so I would prefer to document
at least 3.3 is needed, or similar.

My gcc version is 2.96. I have no heartburn with upgrading to gcc 3.3 if you can
tell me where to get the alpha rpm.

Marked the bug WONTFIX.

We will instead require a minimum gcc version
(3.1) for building NSPR on Linux Alpha.

I'm not that familiar with gcc releases,
so please recommend a minimum version.
I put version 3.1 in my previous comment
just as a placeholder.

I'd suggest gcc 3.3, since 3.1 and 3.2 were never used widely and will 
most likely not be tested properly with mozilla.
