[patch, fortran] Make block names unique

[patch, fortran] Make block names unique

[Thomas Koenig]

[-- Attachment #1: Type: text/plain, Size: 398 bytes --]

Hello world,

the attached patch makes block names unique, so that
-fdump-fortran-original dumps are easier to read.

Regression-tested. OK for trunk?

         * decl.c (gfc_match_end):  Check that the block name starts
         with "block@".
         * parse.c (gfc_build_block_ns):  Make block names unique by
         numbering them.
