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?hp=90eaf19d63952c7df0239dcd7c6c09b4292aa575

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.
