It does appear to be a Fedora vs. RHEL issue. No RPM package actually
provides g++. Instead, it provides /usr/bin/g++. On RHEL's version of
Yum, the provides command appears to use an implied glob pattern of
*g++*. However, Fedora's version of Yum only uses the pattern given as
an argument. Based on what I know of Yum's development, I'd guess that
was a change that happened in Yum 3.1+. In Fedora, either of the
following will work.
$ sudo yum provides /usr/bin/g++
$ sudo yum provides '*/g++'
The second is useful when you don't actually know where the file will be
installed. Both should be run as root, since the file cache will need
to be downloaded and cached (why Yum can't cache to a temporary
location, I don't know).
Thank you for that detail Chris.

I also tried:
yum whatprovides */g++
(without quotes) getting identical results, as well as:
yum whatprovides *g++*
yum whatprovides '*g++*'
yum whatprovides '*g++'
yum whatprovides *g++
each of which provide more false positive matches. I don't know the
purpose of the quotes, but at least in this case (in my bash shell), the
quotes didn't seem to make a difference in any of the combinations I tried.
