[Patch, fortran] PR28817 and PR21918

[Paul Thomas]

:ADDPATCH fortran:

This PR is associated with the warnings produced by -Wunused.  At 
present, gcc/errors.c(warning) is used and this, for some reason, is 
scambling the line numbers.  Tobi Schlueter proposed to use gfc_warning 
in the context of PR21918 and this patch implements that.  The drawback 
is the the gfc warning is a bit less concise than its gcc counterpart; 
maybe we should introduce a %l format, as well as a %L format, for 
locii?  However, the information is correct.  I could not readily think 
of a way to test this.

Regtested on FC5/Athlon

OK for trunk and 4.1?
