# `DispatchGlobalExecutor` checks for the presence of `dispatch/private.h` for
# certain low-level libdispatch functionality, and because the header is
# normally only available on Darwin platforms (it is never installed as part of
# a normal Swift build on any platform), makes certain assumptions about
# symbols available there. However, `dev-libs/libdispatch` explicitly installs
# private headers system-wide for `gnustep-base/libobjc2`, and those get picked
# up during the Swift build. Because of the structure of the header on Linux,
# anyone who has `dev-libs/libdispatch` installed will fail to build.
