It’s a feature of gcc that needs to be enabled at build time - there’s no way 
to enable it for a package independently. The way to achieve package-specific 
options would be to enable posix threads by default and disable pthreads 
support in problematic packages.

Some packages assume there is no pthreads on windows and have their own 
implementation [1] - getting it to work with both can take some time [2]. I 
think there’s a handful of packages that still fail to build with “.posix”, 
once those are fixed we’ll probably make it the default [3].
