Testing remote debugging in the next gdb version:
GNU gdb 5.1.1

This GDB was configured as "i386-pc-msdosdjgpp".
I found that the time-out for waiting response form the target do not work.
This is because in the module ser-go32.c, the funcion rawclock() defined in <time.h> return an unsigned long, and when computing the expresion:
   if ((rawclock () - then) >= 0)
this is always true (although 'then' be defined as long) . I suppose that happen in new versions of gcc only.
The solution is change the expresion above by:
   if (rawclock () >= then)
or (less elegant but easier) put a '#define rawclock (long) rawclock' after the #include <time.h> to force signed the type of the return of rawclock().
Thats all.
