gettext 0.14.5 - some warnings on compiling

[-VASKO-]

I get warnings listed above when compiling gettext 0.14.5-1. I found fix for l10nflist.c here:

http://gcc.gnu.org/ml/gcc/2006-09/msg00646.html

But what about other warnings? I know its appeared because sizeof(wchar_t) on Linux is 4, but on Windows is 2.
Anybody have fixes for these warnings? Maybe I can ignore them? Any ideas or comments? Can you help me?
Thanks a lot.

Consider upgrading.  The latest version of gettext is 0.16.1.

Or for that matter, explain why you need to compile from source.  Cygwin
comes with gettext 0.15 precompiled, so that you need not worry about
compiling it yourself.

I will add this - gettext 0.16.1 built just fine for me out of the box
into /usr/local, but I don't know if I am missing anything important from
Chuck's detailed procedure for getting a release-worthy version into /usr.
 I also know that Bruno has stated that 0.15 is incompatible with automake
1.10, so building coreutils or m4 from CVS requires gettext 0.16 or
greater.  But no pressure on getting a new release made, Chuck :)

It depends on whether the warning was masking a bug or not.  But you are
better off reporting such bugs to the upstream maintainers - oftentimes,
that warning indicates a true bug where someone has compiled on Linux and
used wchar_t when they should have used wint_t, but other times, it is
benign.  What makes this particular error annoying is that there is no way
(except in CVS gcc) to disable it when it is a false positive, and
restructuring the comparison to avoid the warning can sometimes be rather
difficult.

So, to whom I should report about these warnings to get skilled suggestions for fast fixing or confirmations for safely ignoring it? Anybody can really help ? Thanks a lot.

When building a package from the upstream source, the best bet for
compilation questions is asking the upstream source maintainer (ie. by not
using the precompiled cygwin version, you have moved beyond the realm of
cygwin-specific questions that this list covers).  In this case, the
upstream source for gettext is tracked on the mailing list bug-gnu-utils
AT gnu DOT org.
