I was a bit too conservative in my estimation, I'm done with the walkthrough.
I summary, I found 7 packages affected by a false negative on headers
check (mainly for stdbool.h), due to

For now I track the failures through a "meta-bug" in Fedora [1], and
create individual bugs for each package's maintainer individually as
the analysis progresses [2][3][4][5], and if the issue is assumed to
be on their side. Considering the amount of work, I leave the upstream
discussion to the res
There are about 70 softwares (in Fedora ecosystem at least) which are
affected by this comma.
It will be hard for one person to track the upstream for each of them
individually.
I'll probably create issues at the package level on our side, so that
their respective maintainers track the issue with

Could you share the links? Thanks.

Description: Message signed with OpenPGP
Hello,
I may have found a weird one with EGREP_TRADITIONAL.
It'll be hard to have a snippet though, but I'll try to explain.
The apr program has shown a weird behavior during configure execution:
configure:26378: checking whether int64_t and long use fmt %ld
configure:26413: gcc -c -g -O2 -Werr
Thanks, I'll update the bug I opened for them.

Hello again,
One more failure analysis, this time for Wine.
They have the following code in their aclocal.m4{,.cross} files:
dnl Check whether we need to define a symbol on the compiler command

After a few more hours of investigation, the failure in krb5 seems to be
due to a bug in their aclocal.m4 file: a misplaced "fi" similar to the one
fixed by v2.72c-10-g68fac90c: 'AC_FUNC_ALLOCA: fix a misplaced (now fatal)
closing "fi"'.
So I guess I can only dig into the other failures one by one
Hello again,
Some progress on this, it looks like, at least for libpng, there is at one
place where the "Port AC_LANG_CALL" seems to be the culprit.
Specifically, the "," in the C comment, is interpreted by M4 as argument
split which in turn leads to the syntax error.
I made a small test where I
Hello,
In the past few months, I worked on a tool that massively rebuild packages
that depend on a specific other package, in order to help spot problems as
early as possible (on Fedora and RHEL so far).
I used this tool to check whether a new version of autoconf could lead to
