I can't comment on your comments about support, ordering, or NFS, but I
can comment on compiler stuff.  The problem with the compiler is not that
it's a dog, the problem is that it's a pig: it likes to have lots and
lots of memory available.  We're fixing that, though.  The first CSD
features a performance improvement of around 10%, and the next CSD will
have significant improvements in working-set size, which will lead to
better swapper behaviour.  Some of our preliminary tests show compile-
time improvements of around 25% over the first CSD on small machines.
We'll let you know when this is available.  In the mean time, you'll see
big improvements if you jack your machine up to 16M of RAM.  I know that
this is a poor way to fix the compiler's memory allocation problems, but
it *will* give you fast relief.

How do you expect us to fix bugs if you don't tell us what they are?
Build a preprocessed version of your program with the failing code (ie,
compile with -P), and send the resulting .I file to cset2@vnet.ibm.com
along with a covering note telling us where to look for the problem and
we'll open up an APAR and get this fixed in an upcoming CSD.  And btw,
this goes for anyone else with a C Set/2 question, kudo, or complaint...
cset2@vnet.ibm.com is your 24-hour a day hotline to the C Set/2
developers, workframe@vnet.ibm.com for Workframe/2.
