I don't think that is a bug. I believe it is working as intended.
Many header files require other header files to be included first.
One common case is that sys/types.h need to be included before some
other header file is included. sys/select.h apparently needs this.
One might argue that each header file should include all other files it
needs, but that is a policy question and the current policy is to not
do it that way.
