	I just recently installed MicroEMACS 3.8i as my Amiga system
editor, and though the code was already #ifdef'ed for the Amiga, I ran
into a couple of needed alterations for it, so I thought I'd post them.
	The first is a problem that's come up with nearly every release
of uemacs for those of us using Manx. The Manx default is to have the
ctrl-C interrupt enabled, and since ctrl-C is a uemacs command, there's
a conflict. Hitting ctrl-C will bomb uemacs, though not immediately; it
happens on the next disk access, when the system calls Check_Abort(), and
realizes ctrl-C was hit.
	Anyway, the fix is to add the following lines to the termio.c
module:
-------------------------------------------------------------------------
In the ttopen() routine, here's the original code:

#if     AMIGA
        terminal = Open("RAW:1/1/639/199/MicroEMACS 3.7/Amiga", NEW);
#endif

Change it to the following:

#if     AMIGA
	extern	Enable_Abort;	/* Turn off ctrl-C interrupt */

	Enable_Abort = 0;	/* for the Manx compiler */
        terminal = Open("RAW:1/1/639/199/MicroEMACS 3.7/Amiga", NEW);
#endif

Now change the ttclose() routine from this:

#if     AMIGA
        amg_flush();
        Close(terminal);
#endif

to this:

#if     AMIGA
        amg_flush();
	Enable_Abort = 1;	/* Fix for Manx */
        Close(terminal);
#endif
------------------------------------------------------------------------
	The other fix is minor, but worth mentioning: if you turn on the
color option, you'll get peculiar results. It was written for MSDOS
machines, and the color codes are different. For instance, what's
"white" to a PC is "orange" (using the standard workbench color
selections) on an Amiga. Result: all your text will be in orange if you
turn this option on. And the add-mode commands to change colors will
have the wrong names attached to the colors - confusing!
	The fix goes in the edef.h header file. Make the following
changes:
-------------------------------------------------------------------------
Change this:

char	*cname[] = {			/* names of colors		*/
	"BLACK", "RED", "GREEN", "YELLOW", "BLUE",
	"MAGENTA", "CYAN", "WHITE"};

to this:

#if AMIGA
char	*cname[] = {			/* names of colors		*/
	"BLUE", "WHITE", "BLACK", "ORANGE", "BLUE",
	"WHITE", "BLACK", "ORANGE"};
#else
char	*cname[] = {			/* names of colors		*/
	"BLACK", "RED", "GREEN", "YELLOW", "BLUE",
	"MAGENTA", "CYAN", "WHITE"};
#endif

And then change this:

int	gfcolor = 7;			/* global forgrnd color (white)	*/

to this:
#if AMIGA
int	gfcolor = 1;			/* global forgrnd color (white)	*/
#else
int	gfcolor = 7;			/* global forgrnd color (white)	*/
#endif
-------------------------------------------------------------------------
	One final note: you'll need to compile with the long integer
option (+L). Without it, you'll get an error-free compile and link, but
the sucker won't run. If anybody has a fix for *that*, please let me
know. I'm short of space on my system disk, and I'd love to be able to
compile uemacs into a more compact executable.
