What has to be done to add a compilation option ?

[SAUDUBRAY, Fabien]

Hi everybody,

I want to do some hack in the kernel.I want to have the choice to compile
the kernel with or without this option, passing an --enable-xxx option to
the script configure. I 'm a neewbie in autoconf , automake, etc. I had add
some c source in the rtems-4.6.2/cpukit/score/src directory, and some header
file in the  rtems-4.6.2/cpukit/score/include/rtems/score directory. I also
had conditionnal compilation in some c source of the
rtems-4.6.2/cpukit/score/src directory.

I believe that I had to change the files
  rtems-4.6.2/cpukit/configure.ac
  rtems-4.6.2/cpukit/Makefile.am
  rtems-4.6.2/configure.ac
and to had 2 m4 macro in  rtems-4.6.2/aclocal/ and in
rtems-4.6.2/cpukit/aclocal

But at this point I'm not sure if I had to change other files, and moreover
I don't know what to do next ?
