As I understand it, sometimes 'cc' and 'gcc' differ in how structs and
unions are returned/passed from/to functions. To assure that 'gcc' uses the
same technique for programs that do struct passing (like dbm), it's
recommended that -fpcc-struct-return is used. By according to the manual,
it looks as if by default 'gcc' does this:

	  -fpcc-struct-return
	       Use the same convention for returning struct and	 union
	       values  that  is	 used  by the usual C compiler on your
	       system.	This convention	is less	 efficient  for	 small
	       structures,  and	 on many machines it fails to be reen-
	       trant; but it has the advantage of allowing intercalla-
	       bility between GCC-compiled code	and PCC-compiled code.

	  -freg-struct-return
	       Use the convention that struct and union	values are re-
	       turned  in registers when possible.  This is more effi-
	       cient for small structures than -fpcc-struct-return.

Does the above apply to cross compiling only?

Thanks!
