[netCDF #XTD-723603]: problems with ncgen3 passing checks on AIX system

ok, so either the ncgen3 code is too weird (a possibility)
or the xlc compiler is screwed up.
Try gcc if you can. Also, if AIX has gdb
and you are familiar with it, you might see if you
can use gdb to detect where the error is specifically occurring.
