New m4 release was made after a long time, for us most importantly
it ships newer gnulib so it compiles against GCC15 without forcing GNU17.
* Noteworthy changes in release 1.4.20 (2025-05-10) [stable]
** Fix a bug in the `eval' builtin where it does not suppress warnings
about division by zero that occurs within a more complex expression on
the right hand side of || or && (present since short-circuiting was
introduced in 1.4.8b).
** The `syscmd' and `esyscmd' builtins no longer mishandle a command line
starting with `-' or `+' (present since "the beginning").
** Fix regression introduced in 1.4.19 where trace output (such as with
`debugmode(t)') could read invalid memory when tracing a series of
pushed macros that are popped during argument collection.
** Fix regression introduced in 1.4.19 where the `format' builtin
inadvertently took on locale-dependent parsing and output of floating
point numbers as a side-effect of introducing message translations.
While it would be nice for m4 to be fully locale-aware, such a behavior
change belongs in a major version release such as 1.6, and not a minor
release.
** Fix regression introduced in 1.4.11 where the experimental `changeword'
builtin could cause a crash if given a regex that does not match all
one-byte prefixes of valid longer matches. As a reminder, `changeword'
is not recommended for production use, and will likely not be present
in the next major version release.
** On non-Unix platforms where binary files differ from text, loading a
frozen file (which should be cross-platform compatible) now correctly
uses binary mode.
** Several documentation improvements to the manual.
** Update to comply with newer C standards, and inherit portability
improvements from gnulib.

In the light of recent XZ events, and fundamental XZ issues lets work on
moving away from using XZ.
So, use gz compressed tarballs as sources whenever possible.
dwarves only offers bz2 compressed tarballs, so use those as size
difference is minor compared to XZ.

M4 fails to build against glibc 2.16.x, the shipped stdio.in.h attempts to
wrap gets() with a warning which fails since gets() got removed from the
default _GNU_SOURCE featureset.
