- Subject: [PATCH, doc] PR30739: awk is a build prerequisite
I suppose nobody in those PRs (30739, 29049) remembers which gawk
versions were broken, so let's just go for a general mention.
According to 'info gawk SVR4', GCC needs at least SVR4 awk because
multiple -f options, -v, and regex constants are used during the build.
I haven't seen any Posix requirement in the scripts, at a quick glance.
Tested 'make html info pdf'. OK for trunk?
Thanks,
Ralf
