I'm using the following construct in a Makefile to determine which
operating system I'm using:

$(NAME):
	@if uname -s -r | grep "SunOS 4" ; then \
		make -f Makefile.sunos $(NAME) ; fi
	@if uname -s -r | grep "SunOS 5" ; then \
		make -f Makefile.solaris $(NAME) ; fi
	@if uname -s -r | grep "OSF1" ; then \
		make -f Makefile.decosf1 $(NAME) ; fi
	@if uname -s -r | grep "IRIX 5" ; then \
		make -f Makefile.irix5 $(NAME) ; fi

However, if I use the same approach under Linux, uname reports "Linux"
for both a.out and ELF versions.

As I'm using the dynamic loading routines, and need to discern between
a.out and ELF, can anyone suggest a similar, simple scheme so that I may
use either  Makefile.linuxaout or Makefile.linuxelf ?

Thanks,
