Yes, Linux uses gnu89

  .. and that allows plenty of silently accepted extensions, including variable-length arrays, which were in GNU C long before C99. It seems that only GCC 4.3 added the -Wvla option to unbundle the diagnosis of the presence of VLA's from -pedantic. Now you can write in gnu89, while banishing VLA's from your code base, if you're so inclined.
