I am have a problem I think with path statements. I was able to install 
cygwin and recompile a complete set of arm tools using the new cygwin libs.
Now my makefiles run in a cygwin window but fail in Windows CMD line and 
Eclipse.

The make file below is very simple and works in a cygwin window. In a 
dos window the gcc command just returns after doing nothing. In Eclipse 
it returns error 1.
The first item, srt.s appear to correctly compile both in dos and cygwin 
yet fails somehow on the first gcc compile

 'arm-elf-gcc -I./ -c -fno-common -O3 -g main.c'

To complicate things even more, in dos arm-elf-gcc can be found and 
executed returning 'no input files' so I know the path to the executable 
is working

Thanks for any help
JD
