using macro ...

[raespi]

Hi ... I've been googlin' around and I stumbled upon a project called 
XENO for providing a C++ wrapper for Xenomai.   The project's outdated 
and I'm trying to port it to the newer versions of Xenomai and Autotools 
( for the build part ).  I noticed in the configure.ac something like this:

AC_SUBST_INT_HEX

and in the m4/general.m4 file these two lines:

AC_SUBST_INT_HEX(EXPRESSION, HEADER, SYMBOL)
AC_SUBST_INT_HEX(EXPRESSION-AND-SYMBOL, HEADER)

This macro doesn't show up anywhere on the web.  If you search for it 
only 2 links pop up.  Are these macros defined by you ?? If so, how can 
I get them??

Thanks ...
