... for builds using the PCRE bundled with the GLib sources, so that
pcre_version() will also be defined, and be exported so that the regex test program
will properly link when the bundled PCRE sources are used.
This is a follow-up commit to 476f30a.
Use Multiprocessor compilation which can cut down build times by quite a
bit and use the /d2Zi+ flag to have better debugging info being logged to
the .pdb for release builds.
These are only applicable for Visual Studio 2010/2012 and later.
Make the projects include a single property sheet as necessary, which will
in turn include the other property sheet(s) as needed, so that we can avoid
warnings where we include the same property sheets twice in a single
project.
Also make the copying of pre-configured headers into custom build rules so
that they can be removed upon the clean command from the IDE and that they
can be re-copied if their counterpart *.h.win32 are updated.
Like the Visual Studio 2008 project files, split up the property sheets
so to ease maintenace, and to prepare to use autotools to fill in the
header entries to "install".
Put some of the items that are frequently repeated in the projects as well,
also to simplify maintenance.
Also, update the autotools files to automate the upgrade of Visual Studio
2010 project as we now have multiple property sheets to copy and process.
