Intel OneAPI on Windows compile failure

[chuckyvt]

Trying to build NetCDF 4.9.3 in Intel OneAPI 2025.2 on Windows Ran into a couple minor bugs.

In libdispatch\XGetopt.c: Line 270: pointer to integer conversion failure. By changing p on line 252 to a single pointer (char* p) addresses that

ncdump\ncfilteravail.c: Call to undeclared function "_getpid' Add #include "process.h" on line 24 in the #if defiend(_WIN32)... block

Thanks! I've recently integrated the IntelOne compilers into our docker CI, so now we can hopefully catch and debug these things more easily. Thank you!
