Gerald Pfeifer 478a268d25 USE_FORTRAN=yes now implies lang/gcc45 up from lang/gcc44. 
cad/salome and math/freemat needed some adjustments, apart from these
this looks like a far more easy upgrade than previous ones and according
to the upstream developers we do not even need to bump dependent ports
since GNU Fortran 4.4 and 4.5 are sufficiently compatible.

Tested by:	erwin (and pointyhat)

# bsd.gcc.mk - Support for smarter USE_GCC usage.
#
# Created by: Edwin Groothuis <edwin@freebsd.org>
#
# For port developers:
# If your port needs a specific (minimum) version of GCC, you can easily
# specify that with a "USE_GCC=" statement. Unless absolutely necessary
# do so by specifying "USE_GCC=X.Y+" which requests at least GCC version
# X.Y. To request a specific version omit the trailing + sign. Use of
# a Fortran compiler is declared by the USE_FORTRAN knob, not USE_GCC.
#
# Examples:
# USE_GCC= 4.2+ # port requires GCC 4.2 or later.
# USE_GCC= 4.5 # port requires GCC 4.5.
#
# If your port needs a Fortran compiler, please specify that with the
# USE_FORTRAN= knob. Here is the list of options for that knob:
#
# USE_FORTRAN= yes # use gfortran45 (lang/gcc45)
# USE_FORTRAN= g77 # use g77-34 (lang/gcc34; FreeBSD>=7)
# # or system f77 (/usr/bin/f77; FreeBSD<=6)
# USE_FORTRAN= ifort # use the Intel compiler (lang/ifc)
#
# Due to object file incompatiblity between Fortran compilers, we strongly
# recommend to use only one of them on any system.
#
# If you are wondering what your port exactly does, use "make test-gcc"
# to see some debugging.
