As far as LightspeedC is concerned

	Easily 250-500 Lines per second from 800k floppies.  Even faster
	if the compiler and includes are on a ramdisk.

	Unfortunately not as bright as it could be.  Indications are that
	they sacrificed this to meet release schedules.

	They claim complete.  I haven't noticed any inconsistencies.

	As an extra step.  Part of the edit-recompile-test cycle speed
	is that a complete application isn't built for every cycle.  Extra
	time to build a large application is measurable in seconds.
>	5) supports float & double
	Yes.  double is 80-bit extended IEEE (using SANE).
>	6) supports TYPEDEF
	Yes.
>	7) for that matter passing structs by ref?
	Passing of structs by ref and return of structs are both supported.

	In addition:
	1)  Has a blindlingly fast edit/recompile cycle.
	2)  Supports enum, pascal function modifier and inline toolbox
	traps.
	3)  Editor/Compiler are a single package occupying 173K.
	4)  The editor supports unix style full regular expression
	search and replace.
	5)  There is a multi-file search and replace capability that
	is rather well implemented.
	6)  The package has a built in make facility.  It isn't unix
	make, nor is it as powerful, but it quite adequate for it's
	purpose.
	7)  It will generate applications, da's/drivers, and pure code
	resources.  It even allows initialized globals in da's.

	Defects:
	1)  Doesn't yet support added traps in the new roms/HFS.  It
	runs under HFS but you can't write programs to use the new
	calls as delivered.  I have a set of glue routines and header
	files that fixes the problem though.

	2)  Doesn't have inline assembly.  Nor does it integrate well
	with MDS.  You have to assemble the file with MDS and then
	run a program they supply to convert to a useable format.  They
	do provide a method of mapping the single case MDS names to
	the dual-case names they use.

	3)  It breaks when run under heap scramble in TMon which means
	it might have lot's of trouble on a 128K mac or in a small
	switch segment.  The again, so does Finder 5.2.
