IBM has a real problem with proprietary source code.  Think about it from 
their perspective: "We are the world's largest computer company.  Everybody
wants to get us.  If we take your source code "to debug a problem", and at
some point in the future, we come out with a similar product....  Who do
you suppose will be accusing us of "stealing" their ideas?"

In most cases this will not happen; but if IBM "as a policy" accepts 
proprietary source code from other companies, it will show a precedence 
for the court cases that do occur, and leave IBM with its legal butt hanging
in the wind.

To get resolution on this problem you can take two approaches: 1) provide
defect support with a "non-proprietary" testcase that shows the problem.
2) Provide IBM a legal release from liability for using your proprietary
code to debug the problem.  The first method (for some reason) usually
is the prefered method to resolve the problem.  (Most customers just don't
like IBM having their source code.)

For right now, there is no way to get a 'single' fix; except for emergency
fixes.  (An emergency fix, is where there is no update available yet, but the
code has been fixed.)

Think about like this: IBM sends you a new xlc compiler.  2 months later, your
replacement (since you are really talented, and have moved up to management)
calls defect support and reports a bug in xlc.  How does IBM remember that you
got a special fix to xlc 2 months ago.  Now multiply the time by a factor of
years, and the number of fixes by a factor of thousands.  That would be a 
problem management nightmare.  Not to mention the people who get fixes from
"unsupported" routes.  (ie. my friend at "x" company got this fix, and gave it
to me, and I gave it to "y", "z", etc.)  Soon ther would be no way for the 
defect support people to know "what level" your code is at.

IBM markets classes, and provides assistance to companies porting code to the
RS/6000.  Here in Austin, they have a porting center for all companies trying
to move code from other platforms.  They also offer the "System Xtra" support
route, which provides a "single point of contact" for all RS/6000, AIX V3
questions/problems.  The System Xtra offering provides how-to, config, defect,
hardware, updates, everything support through a single 800 number.  The 
System Xtra people dispatch CE's, SE's, and provide on the phone assistance
for any type problems you might run across.
