Something else: the part about xeno-config could lead people to run
xeno-config by hand and paste the result in their makefile, this is not
the way xeno-config should be used, it is better to show people how to
integrate the use of xeno-config in their makefile, as is demonstrated
here:
https://www.xenomai.org/index.php/Porting_POSIX_applications_to_Xenomai#Compilation_flags
The difference is that if we change the flags between two versions of
xenomai, the makefiles should continue to work. We do not consider the
compilation flags as part of the ABI, so, they may change between two
versions.
Also note that starting with xenomai 2.6, pkg-config support is
available, it may make things easier for people integrating xenomai
with autotools based projects.
