Re: superfluous GNUism in the makefile

   It's fine to remove $< from the c/srfi-27.o rule, but doing so
   didn't add portability to the Makefile.in as a whole, while
   trying to achieve such portability will ruin the --srcdir=
   support.  Which is, in my opinion, to high price to pay.

Contrariwise, there are other makes (e.g., BSD make) that prefer to
distinguish the object directory, not the source directory.  But I
guess the conclusion is that make is an incorrigible mess, and I
suppose it's not worth the trouble of trying to be portable.  Oh well.

   Anyway, are there any Scheme48 users with Makes for which this
   Makefile is going to fail?

It is more convenient for users of the BSDs to use BSD make.
