Re: AM_COND_IF for earlier Automake

[Dave Hart]

How is this for a AM_COND_IF that works at the m4sh level on older Automake:

m4_ifndef([AM_COND_IF], [AC_DEFUN([AM_COND_IF],
[m4_ifndef([_AM_COND_VALUE_$1],
          [m4_fatal([$0: no such condition "$1"])])dnl
if test -z "$$1_TRUE"; then :
   m4_n([$2])[]dnl
m4_ifval([$3],
[else
   $3
])dnl
fi[]dnl
])])

I do not know the difference between m4_default and m4_n usage here,
I'm just applying the latest AM_COND_IF changes.  If this code is not
appropriate for Automake prior to 1.11, please let me know.

Cheers,
Dave Hart
