1. Building EUPHORIA with LCC

I tried to compile Euphoria 3.1 with LCC.  It found four syntax errors
which required a type cast from some kind of a pointer (4byte) to an
integer (4byte).  After adding in typecasts to the source, I found that 
there were link errors involving _12dir() and '_current_task'.  
So, I added file.obj and be_task.obj.  I guessed that the BE_FLAGS should
go with be_task and FE_FLAGS with file.c.  The link errors disappeared.

I think LCC might have been abandoned by the time we got to 3.1.  I was
using unmodified original source from the svn in the tag 3.1.

This slightly modified batch file, linked object list file, and two c source
files.  Can be yours if you ask nicely for it. :)

I made exw.exe it works with the demos.  I am happy with it.  It then says
to build your exe file type 'emake'.  I don't understand why I need that.  
What's the exact difference between exw.exe and the resulting int.exe made
by emake?

I went on to do 'emake' and got an error:
'cannot open c:\archivos'

On my system Program Files is not the same but it has a space in it and
something
is not very smart about spaces.  The source of the problem was in lcclnk stops
when it finds any white space when loading a filename.  In other words, it
doesn't
like spaces in its path.  There is a portable hack which will not hurt any
system but will allow users to keep lcc under the Program Files directory like
every other add on program:  For LCC, the path for its library can be made into
a 'short' 8 character long name when an element has a whitespace in it.  This 
even works on NTFS!  This is easy to do, you need to modify c_decl.e.  Warning
I haven't tested this one, I have been using an unportable hack instead but
maybe you want to try it:

function pathnamesTo83( sequence s )
	integer sl, -- slash location
		osl -- old slash location
	if platform() != WIN32 then
		return s
	end if
	osl = find( ':', s )
	if osl = 0 then
		osl = find( '\\', s )
	end if
	sl = osl + find( '\\', s[osl+1..$] ) -- find_from
	while sl != osl do
		if find( ' ', s[osl..sl] ) then
			s = s[1..osl] & s[osl+1..osl+6] & "~1" & s[sl..$]
			sl = osl+8
		end if
		osl = sl
		sl += find( '\\', s[sl+1..$] )
	end while	
	return s
end function

The function is put in the creation of the object for lcc:

printf(link_file, "%s\\bin\\ecwl.lib\n", {pathnamesTo83(eudir)})
