It did for a short time. I assume you use the autoconf CVS repository.
Check out version 1.27 of configure:
cvs update -r 1.27 configure
grep VERSION configure
cvs update -A configure # restore to head configure
grep VERSION configure
This is the autoconf we froze on (at SIM) a short while ago.

Exactly.
: don't understand why you don't use `yes' and `no' for $3. Is this OK?
Well, there might be more attributes I would like to flag in $3 later, so
I chose to use descriptive names.
: define(_SIM_CHECK_COIN_HELP,
: [AC_HELP_STRING([--with-coin=DIR],
: [set the prefix directory where Coin resides [default=$1]])])
:
: AC_DEFUN(SIM_CHECK_COIN,
: [AC_PREREQ([2.14a])dnl
: ifelse([$3], [],
: [$3], [yes],
: [$3], [no],
: [AC_FATAL([$0: invalid attribute `$3'])])dnl
I'm reading up on m4 now. I thought ifelse needed touples of 3 and 3 args to
be used as a switch-case... I'll go back and check this out later - think
I should finish the m4 info-document before implementing this stuff...
Anyways, thanks for the suggested implementation...
