I don't really care, but:

I find this a misleading description. Configure worked just fine on
Solaris, and nothing in your change is specific to Solaris. What this
change really is is "make absence of normal image libraries or their
headers a warning rather than an error".

This stuff was over 6 years old, and was pretty thoroughly debated at
the time, eg:


Solaris is many times less relevant today than it was 6 years ago;
inexperienced builders wondering "why doesn't my Emacs show images" are
likely more prevalent. The point was that such people are liable to miss
a warning flying by amongst the (lengthy) configure output.

I don't think that would be a very good idea...

I'm not sure if there are any platforms where the necessary headers to
compile applications with image libraries are installed by default (but
"installed by default" is nebulous anyway; does it mean a truly minimal
install, a desktop install, server install, workstation install, etc).
