AX_CHECK_STRCSPN
Not all systems have strcspn(3). See if we need to substitute. To make this work, you have to do horrible things. In one of your Makefile.am files, you must make an explicit rule to make this object. It should look like this:
strcspn.lo : $(top_srcdir)/compat/strcspn.c
$(LTCOMPILE) -o $@ -c $(top_srcdir)/compat/strcspn.c
and you must include “@COMPATOBJ@” in a LIBADD somewhere and, finally, you must add another artificial dependency, something like:
makeshell.lo : genshell.c @COMPATOBJ@
It is all pretty horrific, but I have found nothing else that works.
