[ECOS] Problem with 'make tests' for synthetic linux target

[Paul Chakravarti <pc000 at passtheaardvark dot com>]

Hi,

I am just getting started with eCos and have been having problems  
successfully building a eCos test-case  under the synthetic i386-linux  
target using the instructions in the User Guide.

The kernel appears to build successfully using 'make' however when I  
try to run 'make tests' I get an number of undefined reference errors  
to '_Unwind_xxxxx' functions when building 'tests/cxxsupp' (see details  
below).

I am running a clean install of eCos 2.0 on Slackware9 and created the  
project with the command line ecosconfig tool using the i386linux  
target (ie. 'ecosconfig new i386linux' / 'ecosconfig tree' etc.)

Any hints would be greatly appreciated.

Regards,
Paul Chakravarti
