You could use "GENERIC" to generate different versions of "vec" - and make the
two argument version set "z == 0". (Similar to "GENERIC :: OPERATOR(+)" but for
type-bound procedures.)


Are there other issues in the bug report? From comment 0 it is a bit unclear to
me what the issue is - besides the non-issue mentioned in comment 1.

If there is no issue left, I would like to close this problem report (PR).

For general Fortran questions, I would recommend the comp.lang.fortran news
group which is available on *any* (net) news server. It is also available via
Google, but they do not filter spam - thus, your university's or ISP's server
should be preferred. Cf. also http://groups.google.com/group/comp.lang.fortran/

For specific gfortran question, the fortran mailing list at
