s_lock.h problem on S/Linux

Hi hackers.

I am having problems with the new spinlock code on the SPARC linux
platform. (Latest CVSup)

The compiler doesn't seem to like the "asm" part of s_lock.h for (sparc)

Here's one of the compiles that fails.

make[3]: Entering directory `/usr/local/pgsql/src/backend/storage/ipc'
gcc -I../../../include -I../../../backend   -O2  -Wall -Wmissing-prototypes
-I../..   -c spin.c -o spin.o

Th ccsym information may be useful.
