Special code for handling interrupts on Windows systems

[John W. Eaton]

Does anyone understand what problem the w32_* functions in 
liboctave/cruft/misc/cquit.c are trying to solve?  They don't compile 
properly on 64-bit Windows systems because of the use of the Eip field 
in the thread context structure.  A binary that I compiled without them 
for 64-bit Windows (MinGW) appears to handle Control-C interrupts at the 
command line properly.  Perhaps these functions were needed at some time 
in the past, but are they really needed now?
