Subject: Use awk over printf when generating atlocal.
X-Git-Tag: v1.3~71
X-Git-Url: https://git.draconx.ca/gitweb/cdecl99.git/commitdiff_plain/9f003ff99e099ddfe8b8a4af08a447d990705778

Use awk over printf when generating atlocal.

We use awk extensively already and it will do the job here.  SVr4
printf does not implement the POSIX behaviour of repeating the output
when there are more arguments than needed for the given format string.
