GNU 2.7.2.3 compiler

[Dirk Laurie]

I've just upgraded my Linux system to Red Hat 5.0.  Since this upgrades
the libraries, I need to recompile. The gcc compiler is now 2.7.2.3,
which is a little more pernickety than 2.7.2.1.  I get the following
compiler error when compiling octave-2.0.10:

../liboctave/lo-specfun.h:51: previous declaration of `double gamma(double)'
