Re: new snapshot available: autoconf-2.72c

I was able to work around the EGREP_TRADITIONAL issue by reordering
macros. The issue is conditional code blocks which mean
EGREP_TRADITIONAL was not set in some configure option combinations
leading to obtuse failures.

Our testing so far shows the following three sets of issues.


Macro ordering issues with EGREP_TRADITIONAL being unset:

apr 1.7.2
libarchive 3.6.2


Ship with an older gnulib largefile.m4 which breaks with autoconf
2.72c:

parted 3.5
man-db 2.11.2
libpipeline 1.5.7
gzip 1.12
findutils 4.9.0
bison 3.8.2
gettext 0.21.1
coreutils 9.1
wget 1.21.3

On x32 were seeing two recipes which configure "ok" but fail at compile
time:

gpgme 1.18.0
mpg123 1.31.2

Now that things are roughly building, we should get some better
automated runtime testing results in a few hours.

Cheers,
