Yes, that's what I considered doing.

I agree, it considered that as an alternative.


Unfortunately, it is not that simple.
It would be necessary to create several *.pc.in files, one for 
each set of config parameters, cf. the output of xeno-config:
- xenomai-kernel.pc.in <-> --kernel-*
- xenomai-native.pc.in <-> --xeno-*
- xenomai-posix.pc.in <-> --posix-*
- xenomai-uvm.pc.in <-> --uvm-*

Beware that me must "merge" the *-cflags and *-ldflags config 
info, because pkg-config splits them a-posteriori, cf. the 
--cflags, --libs-only-L and --libs-only-l options of pkg-config.
That separation is different from that of Xenomai's xeno-config.


And the xeno-config script would still be necessary for some 
parameters, such as:
    xeno-config --module-dir
and:
    xeno-config --config
pkg-config is too limited regarding the information that we can 
put into .pc files...


Anyway, Stephane, if you want to write the four *.pc.in, go on 
please! :)
