There is no comprehensive language reference available for the GNU
Fortran Compiler, but all intrinsic procedures and extensions are listed
in the manual: http://gcc.gnu.org/onlinedocs/

For the language reference:
http://gcc.gnu.org/wiki/GFortranStandards
gfortran has (modulo bugs) implemented all of Fortran 95 and a bit of
Fortran 2003 (see manual for the implemented features).

See intrinsics documentation in the manual (see above); additionally,
using the "system" intrinsic subroutine or using ISO C Bindings (see
Fortran 2003 standard) you can access (almost) any library function of
your system.

Real world examples (of different quality) can be found at:
   http://gcc.gnu.org/wiki/GfortranApps
(well, they are actually real-world programs and not examples ;-)

Otherwise, have a look around
http://dmoz.org/Computers/Programming/Languages/Fortran/

I can also recommend the book
Fortran 95/2003 Explained by Michael Metcalf, John Reid, and Malcolm Cohen
http://www.oup.com/uk/catalogue/?ci=9780198526933
available in many libraries and bookstores.
