Changing system or user PATH env vars through the control panel
is a *very* bad idea. No single GTK+ version (or anything else
from the GNOME platform stack, like GLib for example) should be
listed in system or user PATH as doing so declares a single 
installation
of the platform stack as the "system wide installed" version.

This conflicts badly with our "each app comes with it's own GTK+
runtime environment" philosophy.

Unfortunately, there are "misguided" installers you might encounter
in the wild that seem to insist on doing this anyway (mono's GTK sharp
used to do this, no idea if it still does), making it next to 
impossible
to know for sure unless you check the validity of PATH manually.

Looks like some other GTK+ installation is also on PATH, before
the entry you added for 2.24.8, resulting in 2.10 getting picked
up instead.

You seem to have both.

The most flexible solution is to build yourself a wrapper script
(.bat or .cmd) or in case you use MinGW/MSYS a shell script, that
exports PATH, PKG_CONFIG_PATH and other search paths you need,
the way you want them to be and from that launch the tool you use
to build you program. Such tool might be an MSYS bash session,
eclipse cdt, codeblocks, ...
