Notes for compiling the RTF distribution under THINK C (6.0).

Build all projects with reader.c and the translator source files in one
segment, and the ANSI library in another segment.

Under Options/THINK C.../Prefix, use the following:

	#include <MacHeaders>
	#define VARARGS
	#define SYSV

For THINK C 5.0, the same prefix is used, but it's found under Options/Prefix.

Under Options/THINK C.../Language Settings (or Options/Language Settings for 5.0),
select THINK C extensions.

All the programs #include console.hand call ccommand() when THINK C is defined,
to allow the user to enter a UNIX-style command line.

Several of the programs formerly used a function named Control().  This conflicts
with a function of the same name in Devices.h, so I changed the programs to call
ControlClass() instead.  Made some other renaming changes for consistency, e.g.,
Text() -> TextClass().


rtf2troff.h:
This uses bcopy(), which is redefined in terms of memcpy() if SYSV is defined.
But under THINK C, must also make sure that the third argument is 4 bytes long,
or the copy gets a bad argument.  Thus bcopy() is defined differently when THINK_C
is defined than when not.

u_long is normaly defined in sys/types.h, but it doesn't seem to be defined in
any header files under THINK_C, so it's typedef'ed directly here.
