Subject: Efl fails in 4.2
Index:	usr.bin/efl 4.2BSD

Description:
	Efl bombs out, even on the simplest files.  It reports something
	like:
		f77 -F  ../gas/gpertsub.e
		File ../gas/gpertsub.e:
		calloc(1024 words)
		Bad count word 1024
		Highwater mark 2384 words. 2155 words left over
		
		***Compiler error on line 15.   Line 15:  out of memory.
		Termination code 11
	and then then goes into an infinite loop.
Repeat-By:
	(file above not included)
Fix:
	The problem is that efl defines its own memory allocation routines
	alloc, malloc, calloc, free, cfree with different calling
	conventions.  Some routine in the C library (probably stdio)
	eventually calls one of the efl routines and corrupts the
	memory allocation arena.  (Actually, it is surprising it worked
	in 4.1.)
	
	To fix the problem, add the following lines (after the #define ALLOC)
	to the defs file:
		#define	calloc	efl_calloc
		#define	alloc	efl_alloc
		#define	malloc	efl_malloc
		#define	cfree	efl_cfree
		#define	free	efl_free
