OK, now to the nasty parts (Gts's sources are quite dirty ;) ):

1. gts-config is buggy:

Compare this (buggy):
$ ./gts-config --cflags
-I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -I/usr/include
$ ./gts-config --libs
-L/usr/lib -lgts -lglib-2.0 -lm

to this:
$ pkg-config --cflags gts
-pthread -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include
$ pkg-config --libs gts
-pthread -Wl,--export-dynamic -lgts -lgthread-2.0 -lgmodule-2.0 -ldl -lglib-2.0

I'd propose to patch gts-config to behave as a wrapper to the corresponding
calls to pkg-config, at least for --cflags and --libs, or to patch out the
-I/usr/include rsp. -L/usr/lib by brute force.

2. The package's Makefiles are broken.
They explictily pass -I$(includedir) through INCLUDES. This overrides the system
include path and can cause nasty side-effects.

3. Building the packages causes GCC to emit quite a significant number of
"punned pointer/strict-alignment warnings". These are likely to break the
package at run-time, esp. on 64bit platforms.

Also worth noting is the configure script playing tricks with CFLAGS. AFAIS,
they seem to be harmless at least on FC5/i386.

So, be prepared to watch PRs coming in ;)

I consider 1. to be a MUST-fix, 2. to be a "I recommend to fix it" and 3. headsup.

APPROVED, provided you fix 1. I am going to attach a patch to address issue 2.
to this PR.

[Besides this, this package is one of those packages applying the weird (IMO
sense-free) Drepper-style shared library names. As this package is an ordinary
library, I am not going to fret over this, this time.]
