RE: Win32 cross compiler for AVR?

["Chris Deighton" <cmd33 at cam dot ac dot uk>]

Hi Jyrki et. al.,

Thanks for the suggestion... I removed the libstdc++ directory, and then:

'configure --target=avr' worked OK (as before).

'make' then failed when compiling libgcc2.c (see below for details). From
looking at the error messages and source files, I don't know why! Any ideas?

I'm also a bit suspicious about the include chain... line 36 of longlong.h
doesn't #include tconfig.h (in fact longlong.h doesn't include ANY files!).
Interestingly, line 36 of libgcc2.c DOES #include tconfig.h. Is something
odd going on here, or am I misinterpreting things?

Finally, I also noticed the error message:
  config/avr/avr.h:1190: parse error before "bogus_type"

Does this mean anything obvious? (Clearly, the compiler's already come
across the '#define int bogus_type' & similar declarations in libgcc2.h, but
I don't know how it's managed it before avr.h!)

Thanks everyone for your continuing assistance,

Chris.
