Building GDB-6.3 for powerpc configuration

Andrew, 

Appreciate your quick response, but the "make check" command is also
giving me the following errors, which is dampening my confidence in the
earlier build.. 

$ make check > ~/checkgdb.txt
WARNING: Couldn't find the global config file.
WARNING: Assuming target board is the local machine (which is probably
wrong).
You may need to set your DEJAGNU environment variable.
WARNING: Testcase compile failed, so all tests in this file will
automatically fail.
ERROR: (timeout) GDB never initialized after 10 seconds.
WARNING: remote_expect statement without a default case?!
ERROR: couldn't load
/cygdrive/u/sw0/host/tools/coreDumpAnalyzer/gdb-6.3/gdb/testsuite/gdb.as
m/asm-source into
/cygdrive/u/sw0/host/tools/coreDumpAnalyzer/gdb-6.3/gdb/testsuite/../../
gdb/gdb (end of file).

What is the global config file and what should I set the DEJAGNU
environment variable to?? Does CYGWIN has support for the gdb
test-suite??

Regards,
Manish.

The stabs debugging format only supports upto 65535 lines (hmm 16bit 
unsigned ...).  Unless you're going to try debugging that file it isn't 
that important (it can be solved by specifying dwarf 2 debug format - 
see GCC and the -g option).

These a Altivec instructions and not part of a core PPC, hence the're 
dropped.  Again not an immediate concern.
