System: RS/6000 running AIX 3.2.3
Problem:  Using 'gcc -pg' causes errrors from the assembler.
Fix:

1) You need to install IBM PTF U407530.  This includes a patch
to /bin/as to accept a "-u" flag (APAR IX23433).

2) See patch following for config/rs6000.h - basically, there were
two changes that needed to be made.  

The first was that we have to change ASM_SPEC to pass the "-u" flag to
/bin/as (note that this *WILL BREAK* gcc if U407530 isn't installed -
so don't do this until you get and install that fix first).  I freely
admit that I did NOT fully delve into the comment just above,
concerning ASM_OUTPUT_EXTERNAL and friends.  However, it seems to work
OK.

The second problem was that the IBM /bin/as doesn't like to see a
".space" in what it thinks is a ".toc" scope.  The fix for that was to
generate a ".csect" before .space.

Warrantee:  The code changes *seem* to work.  However, I have *NOT*
tested them against 'gdb' or other tools, etc.. It *does* produce
something that 'gprof' is happy with tho. ;)
