I am working on cleaning up my GHC cross-compiler for QNX (Blackerry 10) and encountered the following from ./configure --target=i486-pc-nto-qnx8.0.0 --build=i686-linux-gnu --host=i686-linux-gnu :

checking sys/eventfd.h usability... no
checking sys/eventfd.h presence... yes
configure: WARNING: sys/eventfd.h: present but cannot be compiled
configure: WARNING: sys/eventfd.h:     check for missing prerequisite headers?
configure: WARNING: sys/eventfd.h: see the Autoconf documentation
configure: WARNING: sys/eventfd.h:     section "Present But Cannot Be Compiled"
configure: WARNING: sys/eventfd.h: proceeding with the compiler's result
configure: WARNING:     ## ----------------------------------------------- ##
configure: WARNING:     ## Report this to glasgow-haskell-b...@haskell.org ##
configure: WARNING:     ## ----------------------------------------------- ##
checking for sys/eventfd.h... no
checking for eventfd... no

What does this mean?  Is it a problem?
