Xcode recently changed the default C language dialect to C99. Many
Xcode users (such as myself) have little to no understanding of what
is new or changed with C99. You can read the 100+ page spec and try
to infer the changes, or you can google "C99" looking for an
informative overview, which results in mostly not very informative
hits.
It took a while but I finally did uncover a really good series of
articles written by Randy Meyers for the C/C++ Users Journal several
years ago. Posting these here in case you have been thinking of doing
the same in the near future:

GCC 4.0 and C99: http://gcc.gnu.org/gcc-4.0/c99status.html
If that's not enough, you can read an annotated book on the standard
(1500+ pages long): http://www.knosof.co.uk/cbook/cbook.html The
publisher backed out so the author published it on the web. There is
a discussion on every line of the C99 standard (which is thus
included).
