[Iverilog-devel] Do we still support systems without inttypes.h?

[Martin W. <mai...@ma...>]

There are a number of places in the Icarus code where a pointer is cast to an 
integer or vice versa. Currently the code uses a long or unsigned long integer 
for the purpose. This doesn't work in 64-bit Windows, because the Windows ABI 
requires long integers to be 32 bits. The proper solution is to use the 
intptr_t or uintptr_t types.

In parts of the Icarus code, there are tests for HAVE_INTTYPES_H, but in other 
parts things from inttypes.h (e.g. int64_t and uint64_t) are used 
unconditionally. What is the current policy on this?

I would guess that any compiler that supports the C++ features we use is also 
going to have inttypes.h.
