[Gm2] Possible bug when using -fmakeall / ncurses example

[Christoph Schlegel]

Hello Gaius,

another report after testing the newly built gm2 compiler on Cygwin32.

The following error occured when I tried to compile the ncurses-example. Note 
the command 'home/Christoph/opt/lib/gcc//i686-pc-cygwin/4.7.3gm2 -c etc.' where 
a slash seems to be missing. I remember a similar problem which appeared a few 
months ago (http://lists.gnu.org/archive/html/gm2/2014-01/msg00003.html). I 
tried and the example code from back then compiles now. I guess the Makefile 
created by -fmakeall carries some bug within. I really tried to provide more 
but I cannot reproduce/understand the way -fmakeall works, so here is the 
error:

And a sidenote: A small change that could be made to be more compatible with 
platforms like Windows: Using the size command results in an error when called 
like in the hello world example of gm2. It could be written like: 'size 
a$(EXEEXT)' instead of 'size a.out' to take care of the Windows .exe extension 
(for example in the Makefile of the hello-example, lines 37, 39, 43 and 45).

And one more thing, I forgot to wish you a merry christmas and a happy new year 
- just wanted to catch up...

Regards,
Christoph
