1. strange bug
I have written a console application for windows. The binded it and it works
fine. The I decided to convert to C using ecw.exe. When I run the conververted
version I have to press <ENTER> two times to confirm a line input.
I tested it with another console application and have the same bug. Both use
get_key() to read the keyboard input.

2. Re: strange bug
here a sample code to demonstrate the bug.
--testing
function input_line()
integer c
sequence line
line = ""
c = get_key()
while c != 13 do
if c >= 32 and c<=256 then
line &= c
puts(1,c)
end if
c = get_key()
end while
puts(1,'\n')
return line&'\n'
end function
sequence iline
iline = input_line()
while length(iline)>1 do
puts(1,iline)
iline = input_line()
end while
if executed as exwc test_input.exw, it works fine.
translate it to C and run the executable.
Then one have to press <ENTER> two times to complete to exit input_line()

That's a known bug when you translate and compile with Borland (or Lcc).
From my old rough notes (which I should really add to SourceForge):
"Things compiled by Borland (or Lcc):
get_key() requires an extra keypress (even Shift key is enough)
before it responds to the first keystroke.
gets(0) and getc(0) seem ok."
I don't know how to fix it.
Maybe someone can read the Euphoria source and figure this out.
