I see this is a failure in building the tests. There's something weird 
going on here. CYGBLD_MICROWINDOWS_ECOS_APP has a custom build rule to 
build src/ecos/ecos_app.c, which is the only file in microwindows which 
defines gettimeofday. Your only alternative to build the eCos tests would 
be, like Andrew said, to include SNMP which also happens to contain a 
compatibility version of gettimeofday, but that doesn't work either.

I don't know why, if Microwindows needs those functions, they aren't 
included with the rest of the port, rather than in ecos_app.c. Gary, any 
insights?
