1) The AIX sh/bsh/ksh "stupidity" isn't IBM's fault.  Apparently, POSIX
requires that "/bin/sh" point to a POSIX (read: ksh) shell.  Configure
trips over the few places where bsh and ksh differ.

2) At least at some levels of AIX 3.2.x (and maybe 4.1.x), there was a
nasty bug in bsh/ksh that caused erroneous evaluation of expressions of
the form ${x}_${y}, causing Configure to roll over and die with a
syntax error.  I'd cite the APAR/PTF numbers, but it's been fixed for so
long that I've forgotten ;)
