These contain some important DOS era encodings, which are still in use
in localized versions of Windows. As an example, polish version of
Windows 7 expects CP852 to be used in batch/cmd files.

CP{437,737,775,852,853,855,857,858,860,861,863,865,869,1125}
Without it, build is failing to generate executable.
Hidden dependencies are frustrating.

'libintl_' prefix, like in all MSYS modules which use it.

* some whitespace fixes
Remaining md5sums either didn't download or
didn't pass checksum tests.
