i18n problems with comments from multiple files

[Christian Neumair]

Over at AbiWord we have some serious problems:
Comments are enourmous important for us since they contain keywords for
our i18n mechanism that e.g. influence our i18n statistics.
Today I tracked down a problem:
If multiple files contain a comment that affects the same string,
xgettext only writes the first file's comment into the resulting file,
which means
test1.h:
/* first comment */
N_("some string");

test2.h:
/* second comment */
N_("some string");
being in POTFILES.in will result in a POT file containing only "first
comment" as some string's comment.
Is this supposed to be a bug or am I doing something wrong?
