Comment (by mmadia):
This might be the reason why the included headers are different than what
is expected/needed...
First, [libroot's Jamfile http://cgit.haiku-
os.org/haiku/tree/src/build/libroot/Jamfile#n79] sets USES_BE_API on
librootSources.
The entire implications of USES_BE_API is still unclear, but it seems that
at least it's responsible for including build/posix/ and build/os/.
For non-BeOS compatible hosts, [BuildSetup http://cgit.haiku-
os.org/haiku/tree/build/jam/BuildSetup#n914] sets HOST_BE_API_HEADERS to
include both build/posix, build/os/, and other directories.
In MainBuildRules, [rule BuildPlatformMain http://cgit.haiku-
os.org/haiku/tree/build/jam/MainBuildRules#n606]
propagates USES_BE_API to the objects in librootSources.
Then finally in OverriddenJamRules, [rule Object http://cgit.haiku-
os.org/haiku/tree/build/jam/OverriddenJamRules#n94] adds
HOST_BE_API_HEADERS to sysHeaders.
Adding an Echo at line 99, this output snippet backs this idea up

Does this sound correct?
