Subject: | Bug using rawclock() function in module ser-go32.c |

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

There is absolutely no warranty for GDB. Type "show warranty" for details. 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.
