Re: GDB for PE/Cywin target won't build on linux

[Stephen Smith <ischis2@home.com>]

Since the embedded target OS is close to windows/cygwin in functionality, I choose to
try the config/i386/cygwin.mt  file.

Therefore, I added the following line to configure.tgt
 i[3456]86-*-pe*)        gdb_target=cygwin ;;

I then did the usual configure/make step and recieved the following error sequence.  The wierd pard is that the missing
symbols are in gdb/win32-nat.c which isn't getting compiled.    The file is listed in the ALLDEPFILES, but isn't listed
in TSOBS, COMMON_OBS, or ADD_FILES.

Am I correct in assuming that it needs to be listed somewhere else?  Is there a gdb way, or should I do what looks good.
