GCC depending on perl?

[Andrew Cagney]

Hello,

I've noticed several recent changes to GCC have effectively added a 
dependency on PERL.  Well, to be exact, it looks like configure probes 
for perl and certain features and then adjusts the build accordingly.

This just strikes me as strange since PERL isn't listed in the tools 
that can be used in a Makefile.
http://www.gnu.org/prep/standards_52.html .
I'd have only expected such a dependency to be added when something like 
--enable-maintainer-mode was explicitly specified as part of the 
configuration.

enjoy,
Andrew
