[pph] Add one failing C test

[Diego Novillo, 2011-06-01 17:52:29]

This is the last of the large set of failing single-file C test cases I had
collected.  It still fails, but given that we are more people that may
be hacking on the branch now, I wanted to put it out there so I don't
have to keep testing my private set of files anymore.

This fails on read with:

c120060625-1.h:10:22: internal compiler error: invalid built-in macro
"__FLT_MAX__"
