Updated: pkg-config-0.20-1

The pkg-config program is used to retrieve information about installed 
libraries in the system, including the CFLAGS, LDFLAGS, and other 
information necessary to compile and link against one or more libraries.

Technically, this is a "new package", as the upstream maintainers have 
renamed "pkgconfig" to "pkg-config", presumably to avoid the confusion 
inherent in the fact that the executable was ALWAYS named "pkg-config", 
and the relevant environment variables all started with PKG_CONFIG_.  So 
at least now the name of the package and the name of the executable match.

Of course, the default data storage location, /usr/lib/pkgconfig/ has 
NOT changed, so the new version will continue to work with the installed 
.pc files used by the old version.

This upgrade should be relatively smooth, since I have simultaneously 
released an "updated" pkgconfig-0.17.2-3 which is empty, marked 
_obsolete, and requires: this new pkg-config package.

Note that the new "private libs" and "private requires" features do not 
work as they would on *nix systems in this release, because this 
pkg-config was compiled with the --enable-indirect-deps option.  This 
option is necessary to properly link dependent DLLs on MSWin/cygwin, but 
means that no library dependency is truly private.  However, .pc files 
that use the .private options will work properly -- as defined on the 
MSWin/cygwin platform: private libs will be folded into the public libs 
list, and private requires will likewise be folded into the public 
requires list.
