Re: pkg.m4 missing in pkg-config v0.28 tool download for GTK+ 3.x on win32

[Legorol <legorol san gmail com>]

Two more issues on the win32 download page for GTK+ 3.x:

The libpng 1.5.14 run-time download file from
http://win32builder.gnome.org/packages/3.6/libpng_1.5.14-1_win32.zip
is garbled. The contents of the zip file is nonsense when opened with
Windows 7's built-in zip handler. The Dev and Sources downloads are
fine.

All three links for gettext-runtime 0.18.2.1 are incorrect. All three
point to downloads for 0.18.1.1-2.

The all-in-one bundle for 3.x seem to contain the correct files for
libpng 1.5.14 and gettext-runtime 0.18.2.1.

I have not checked the win64 page.
