automake-1.16: aclocal is unable to process AM_PATH_PYTHON with variable as value

[Thomas Deutschmann]

Hi,

with automake-1.16, code like

AM_PATH_PYTHON([$PYTHON_VERSION])

or

AM_PATH_PYTHON([$PYTHON_MIN_VERSION])

as found in

https://gitlab.com/cryptsetup/cryptsetup/blob/master/configure.ac#L506
https://github.com/ImageMagick/PythonMagick/blob/master/configure.ac#L42

***** aclocal *****
***** PWD: /var/tmp/portage/sys-fs/cryptsetup-2.0.1/work/cryptsetup-2.0.1
***** aclocal -I m4
/usr/bin/m4:configure.ac:506: bad expression in eval (bad input): ($+1) != (2)
/usr/bin/m4:configure.ac:506: bad expression in eval (bad input): (0r36:PYTHON_+1) != (0*4)
autom4te-2.69: /usr/bin/m4 failed with exit status: 1
aclocal-1.16: error: echo failed with exit status: 1

I am running into this same problem in one of my projects.

Looks like the reversion of 1d60fb72168e62d33fe433380af621de64e22f23
has fixed this problem and I can build my projects again.

Is there an ETA for a point release containing this fix?

Cheers

I hope to release it next weekend.
