I assume you checked in the following change to fix this problem?

Why did you use (for example)

  #include "stdlib.h"

instead of

  #include <stdlib.h>

?  Is this needed because some system C++ <cXXX> headers don't include
the corresponding C <XXX.h> header files?  If so, then maybe we should
be rethinking the way we use the C system headers throughout Octave.

Also, even though we may expect these headers to be coming from gnulib now,
if we had a system that did not need gnulib to provide proper
POSIX support, I think we would want the <...> style of include
statements.  Won't it work properly to include them with <...> now
given the -I flags we provide to the preprocessor?
