[Bug fortran/24917] New: Handling of hexadecimal constants in gfortran

["iev at hpclab dot ceid dot upatras dot gr" <gcc-bugzilla at gcc dot gnu dot org>]

Compilation of the following program TEST.f fails:

PROGRAM HEX_TEST
INTEGER(4) MASK
MASK = 'c0'X
END

~ $ gfortran -c TEST.f
 In file TEST.f:5



      MASK = 'c0'X
     1
Error: Unclassifiable statement at (1)

whereas the following code compiles correctly:

PROGRAM HEX_TEST
INTEGER(4) MASK
MASK = X'c0'
END

As stated in http://gcc.gnu.org/ml/fortran/2005-11/msg00382.html, the first
version of the code is an extension which was supported in g77, therefore it
should also be supported in gfortran.

The compiler I used to test this is:

~ $ gfortran -v
Using built-in specs.
