building for mingw x xscale

[James Lemke]

With Mark Mitchell's patches, configure & build for
--build=i686-linux-gnu --host=i686-pc-mingw32 --target=xscale-elf has
gone pretty well.  However, there's lots of trouble in gdb/rdi-share
with messages like:

../../../gnu-mingw/gdb/rdi-share/etherdrv.c:52:23: angeldll.h: No such file or directory
../../../gnu-mingw/gdb/rdi-share/etherdrv.c: In function 'fetch_ports':
../../../gnu-mingw/gdb/rdi-share/etherdrv.c:357: warning: pointer targets in passing arg 1 of 'strcmp' differ in signedness
../../../gnu-mingw/gdb/rdi-share/etherdrv.c: In function 'read_packet':
../../../gnu-mingw/gdb/rdi-share/etherdrv.c:421: error: 'pfnProgressCallback' undeclared (first use in this function)
and
../../../gnu-mingw/gdb/rdi-share/unixcomm.c:29:23: termios.h: No such file or directory
../../../gnu-mingw/gdb/rdi-share/unixcomm.c: In function 'Unix_OpenSerial':
../../../gnu-mingw/gdb/rdi-share/unixcomm.c:254: error: 'O_NONBLOCK' undeclared (first use in this function)

Can anyone offer clues about angeldll.h and where it can be found?
Or pfnProgressCallback?

TIA,
Jim.
