Problems calling external C# application from makefile

[David Cowan]

I have a small C# application that I want to call from a makefile.  The 
application runs correctly when run from a batch file, and when run from 
a Windows XP command line.
However, when attempting to call the application from within a makefile 
- the application fails.

Now - this is probably down to something I'm doing somewhere in either 
the makefile or the C# app - but I'm damned if I can spot it.

I've tried running "make -n > test.bat" and running the .bat file by 
hand - and it works fine.   Running the C# app directly from the 
makefile fails.

The C# code is fairly simple... it just uses class serialization to load 
an XML file.

Nothing particularly special - it all just works fine outside of make.

However - running the C# exe from within make results in the following 
error...

I'm running make 3.80, and I'm using Windows XP (SP2).  I'm running from 
an XP DOS Cmdline.

Is there any difference in the executable environment set up by make?

Thanks in advance.
