GDB problems

I'm building Win32-LynxOS cross debuggers out of b18 and having
the following problems:
1. Missing function
gdb/utils.c complains a missing function of "win32pollquit" which
it makes a call to.
I replaced the function with a stub and succeeded in building...
2. GDB crashes in ScreedRows()
This reports a segmentation violation error.
This seems to be a DLL function. I relaced the call with a default
constant value of 24 and ScreenCols() with 80 and it no longer
crashed.
3. GDB doesn't honor ^C
Now I can debug a LynxOS process over TCP/IP, but if the process
enters a blocking system call (like sleep()), hitting ^C at
GDB is no use. (This may be related to the first problem.)
I'm using a Pentium NT box with 32MB. Does anyone have similar
symptoms (and solutions!)?
Thanks.
