/*
.. additional piece, which probably belongs in a "README" somewhere, is that
AIX/370 installers should use the latest (update U401215) C compiler, which
for some inscrutable reason was hidden when installed ("ls /lib/hc*@" is
the key to finding it). The symptom for not doing this is that compiling
some of the generated .c files may take hours rather than seconds (!).

/* Possible change necessary to c/sfasl.c
mckenney@rpi.edu reports the following change necessary
for c/sfasl.c. I (wfs) compiled all of scratchpad (800 files)
and ran many tests without it. I don't have a machine here to
test on, so I am leaving it out till I get confirmation that it is
necessary (I hate to mung up c/sfasl.c any more than it is)
