Yeah there are two main issues with POSIX:

- versions, which means you never know how compliant a given system is

- like C, the standard allows for implementation defined behaviors

In the end #ifdef all the way, no different than using a non-POSIX system.

I direct you to the POSIX makefiles of DMD, druntime, and phobos. ;)

Which as far as I am aware only work on POSIX == Linux.

Er... they work on Linux, OS X, FreeBSD, OpenBSD, Solaris/SunOS.

Ok I was a bit stupid with my remark, sorry about that.

Anyway, I remember when I tried my toy experiment with porting DMD for Solaris I had to do some patches.

You would be surprised what commercial UNIX systems understand as POSIX vs what the standard says. Somehow I don't miss my days porting software among UNIX platforms.

All D toolchain makefiles should work fine on Solaris out of the box now - at least the latest version of the OS.

Well, I was going to tackle the porting stuff about a week ago, but for some reason my computer refuses to boot Haiku, I think it's an ACPI thing, but I can't find any settings for it in my BIOS. Oh well, I guess it will have to wait a while. Or alternatively I could port it from virtualbox or something!

Anyways, eventually I'll get around to it somehow :)
