I understand this vision :-) But that leads into the business of analyzing
the declarations in header files, which requires either a good parser
(capable of analyzing #ifs, so as to simulate the declarations that gcc
would see) or some superficial analysis, which breaks as soon as macros
that expand into __attribute__(...) are used.

Neither of these two choices are appealing to me. So I'm doing the maximum
I can do in this direction, namely introduce a new macro AM_XGETTEXT_OPTION.
