   The rule for the SRFI 27 library in Scheme48's makefile refers to the
   GNU-specific `$^' variable.  Since there is only one source file to
   which it refers by that variable, you can just substitute `$<', which
   is in POSIX.

Sorry, this is wrong: $< is not defined (except by accident) outside
of a prefix rule.  But anyway, you can just substitute the name of the
source file, c/srfi-27.o, and avoid any of these problems.  The same
goes for the other rules that use $<, except for the .c.o prefix rule,
which can still use it.
