Bug ID: 89103
Summary: Allow blank format items in format strings
Product: gcc
Version: 9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran

Patch to allow blank item in format
gfortran as of revision: svn+ssh://gcc.gnu.org/svn/gcc/trunk@268360
At the end of list of specifiers a blank item can appear between the comma and
closing bracket.
The following error is produced, as it should be:
18 | 10 FORMAT( I5,)
| 1
Error: Unexpected element ')' in format string at (1)
In legacy Fortran this is not the case PGI Fortran 18.10 silently accepts this
with no compiler switches. I believe this is feature originated from DEC
Fortran.
Attached is a patch that will allow this.
As this is non-standard Fortran this feature is only enabled using
-fdec-blank-format-item which is also enabled by -fdec.
