No real step-by step introduction, but
a) Reading gcc/ABOUT-GCC-NLS
b) Modifying gcc/po/exgettext

In the latter, one takes care that %e... get properly tagged; see the function
"keyword_option" which tags them as c-format / no-c-format /
gcc-internal-format.

See also
http://www.gnu.org/software/hello/manual/gettext/xgettext-Invocation.html and
http://www.gnu.org/software/hello/manual/gettext/c_002dformat-Flag.html

As blunt solution, one could simply do what as proposed in comment 5: Add the
--keyword= lines to gcc/po/exgettext to the invocation of $xgettext.

A more advanced solution is to do what has been suggested in comment 6;
however, that does not fit the current use of messages in gfortran. What has
been done there is described in gcc/ABOUT-GCC-NLS.

For instance one calls in gcc:
  error ("register name not specified for %q+D", decl);
The function prototype is:
  void error (const char *gmsgid, ...)
Here, "msgid" triggers the the matching in "exgettext" and "g" indicates that
it is not a default C format string but a special one (cf. description in
ABOUT-GCC-NLS).

Seemingly we already ue "msgid", but not with the proper prefix:
  gfc_notify_std (int std, const char *nocmsgid, ...)
"nocmsgid" is currently translated to "no-c-format" but we want to have
gcc-internal-format or gfc-internal-format. The current matches are
(gcc/po/exgettext's function keyword_option):

    if (args ~ /g$/)
        format="gcc-internal-format"
    else if (args ~ /noc$/)
        format="no-c-format"
    else if (args ~ /c$/)
        format="c-format"

Thus "gmsgid" would be one solution or "gfcmsgid" another with adding a
    else if (args ~ /gfc$/)
        format="gfc-internal-format"

Thus, fixing error.c and possibly editing gcc/po/exgettext should be enough.
