I have successfully run under GDB 4.18 programs that use setitimer, so 
interrupts are not disabled in general under a debugger.  Also, SIGINT 
uses the keyboard interrupt, so if your program gets SIGINT when run 
under a debugger, interrupts are not disabled.

What version of the library (libc.a and libdbg.a) was used to compile
RHIDE and/or GDB?  Are the GDB sources you used up-to-date (i.e., from 
gdb418s.zip on SimTel)?
