AC_LTDL_SHLIBEXT setting LT_MODULE_EXT with wrong extension on mac os x

[Husam Senussi]

Hi,

Not sure if this question for autconf, but I'm using AC_LTDL_SHLIBEXT  
to set shard object
extension but I end up with LT_MODULE_EXT set to ".so" in mac os x   
instead of .dylib.

This part of my configure,ac


AM_INIT_AUTOMAKE(foreign)

# Checks for programs.
AC_PROG_CC

AC_PROG_LIBTOOL
AC_LTDL_SHLIBEXT
# Checks for libraries.


anything I need to configure !!

Thanks
