[Sulong] unistd.h does not exit on Windows

[oroppas]

… so the building of sulong fails:

Building com.oracle.truffle.llvm.libraries.bitcode with GNU Make... [rebuild needed by GNU Make]
C:\msys64\home\ryuta\packages\graal\graal\sulong\projects\com.oracle.truffle.llvm.libraries.bitcode/src/fork.c:31:10: fatal error: 'unistd.h' file not found
#include <unistd.h>

Sulong has some OS specific components. Currently it works only on Mac and Linux.

Windows support is planned, but I can't give you a concrete ETA yet.

Windows support is planned, but I can't give you a concrete ETA yet.

Has there been any progress on that matter? Thanks!

PS: I am not sure whether this is my actual root problem (see #1675, compilation of my Quarkus app fails due to missing unistd.h).

We are adding Windows support in the 22.3 release, see #5007.
