Hello!
It is quite annoying to get warning messages like this one:
checking symbol names produced by gcc... shift: shift count must be <= $#
sym
Bash (at least version 1.14.7) is sometimes too verbose.
Since I touched the responsible macro and needed to retest it anyway, I
also simplified a pipe used to scan conftest.s
Patch attached. Now with ChangeLog.
