If you mean to write a portable D library,
then please try to avoid hardcoding linux...


Something that should work is:

But if you use "linux", then your code will *not*
compile on BSD - even if it is plain old POSIX ?


If you *do* use Linux-specific system / OS values,
then by all means continue to use "version(linux)"

And if you need stuff specific to GDC / GCC, then
you can use the handy "version(GNU)" that it sets...


But otherwise, "version(Unix)" should do just fine ?

PS. Apple Mac OS X is such a BSD variant... (called Darwin)

Actually it isn't fine.
GDC defines linux(where appropriate) and Unix - in contrast DMD only
defines linux. For the time being everyone should add

# version(linux){
#     version=Unix;
# }

into the head of each source file ...
Seems to be worth a feature request, doesn't it?

Aargh! That's even worse than the lower-case "linux"

It could well be that GDC already patches this in
Phobos, so that was why I didn't even notice it...

Note to self: test with the linux DMD compiler too.


I suppose that:

could also be used as a work-around meanwhile ?
(better than hardcoding "linux", at any rate)

It does. Or even a bug report.
