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
