gettext 0.11.1 - C99 compiliation issue

[Trond Eivind Glomsrød]

When using the option "-std=c99" with gcc 3.0.4 (and 2.96RH, as well. I 
don't think egcs supported that option), gettext 0.11.1 doesn't compile:

/bin/sh ../libtool --mode=compile gcc3 -DLOCALEDIR=\"/usr/share/locale\" 
-DGETTEXTJAR=\"/usr/share/gettext/gettext.jar\" -DLIBDIR=\"/usr/lib\" 
-DGETTEXTDATADIR=\"/usr/share/gettext\"

The error seems to be at  src/po-lex.h, macro po_gram_error_at_line in 
case __STDC__ && (defined  __STDC_VERSION__ && __STDC_VERSION__ >= 199901L:

(that is, the part actually aimed at doing something specific for C99)
