Hello,
in order to build sedutil (https://github.com/ChubbyAnt/sedutil) on
Fedora 30 I encountered a build error in m4-1.4.18.
Error Message:
freadahead.c: In function 'freadahead':
freadahead.c:92:3: error: #error "Please port gnulib freadahead.c to
your platform! Look at the definition of fflush, fread, ungetc on your
system, then report this to bug-gnulib."

This error occurs because I have glibc-2.29 installed on my Fedora 30
system instead of glibc-2.27 on e.g. Ubuntu 18.04 LTS.
Apparently this is a known issue introduced by a change in glibc-2.28. I
guess it can be patched similar to these two commits in gnulib.
https://github.com/coreutils/gnulib/commit/4af4a4a71827c0bc5e0ec67af23edef4f15cee8e#diff-5bcce8ce55246264586c4aed2a45ff89

Although I am very new two building from source, I hope I can could help.
Best regards,
Marius
