Summary: Warning of AINT as actual argument ain't right
Product: gcc
Version: 4.6.0
Status: UNCONFIRMED
Keywords: diagnostic, documentation, wrong-code
Severity: normal
Priority: P3
Component: fortran
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: burnus@gcc.gnu.org

lnblnk is a GNU extension.
char, ichar, int, and len_trim are also rejected by other compilers.
Currently, gfortran prints the warning
Warning: Interface mismatch in dummy procedure 'fun' at (1): '%s' has
the wrong number of arguments
for the intrinsics aint, anint, index, len and nint.
"13.6 Specific names for standard intrinsic functions"
Speci\fc Name Generic Name Argument Type and Kind
AINT AINT default real
ANINT ANINT default real
INDEX INDEX default character
LEN LEN default character
NINT NINT default real
The problem is that all those functions have an optional KIND= argument -
which, however, is not included in the specific functions (as backward
compatibility to Fortran 77). Thus, the warning is bogus - but another question
is whether this can lead to wrong code by not passing NULL as second argument.
I have not checked, but maybe the documentation should also be improved (cf.
James' posting to c.l.f)
