You shouldn't have to check LessTif vs. Motif.
You certainly don't want your code to rely on
the LESSTIF_VERSION etc. macros.
Whether you use something like AC_CHECK_LIB for
one of the Xme functions, or you write your own macro
to check whether XmVERSION is 2 or higher,
should give the same result.
AC_CHECK_LIB is easier to use than writing your own
macro. Hint hint.
Note that I'm still a LessTif core developer. If you
have problems with LessTif, please send mail to
[EMAIL PROTECTED] . We'll help.
