During libgcc build the first include search path for <...> is "../newlib/libc/sys/rtems/include". Move all RTEMS specific header files to "libc/sys/rtems/include" so that they can be found. Later during libc build the header files in the previous location were somehow present, but for libgcc build they were invisible. This change is necessary to use <pthread.h> for the GCC thread model implementation. newlib/ChangeLog 2015-07-27 Sebastian Huber <sebastian.huber@embedded-brains.de> libc/sys/rtems/machine/_types.h: Move to ... libc/sys/rtems/include/machine/_types.h: ... here. libc/sys/rtems/machine/limits.h: Move to ... libc/sys/rtems/include/machine/limits.h: ... here. libc/sys/rtems/machine/param.h: Move to ... libc/sys/rtems/include/machine/param.h: ... here. libc/sys/rtems/sys/cpuset.h: Move to ... libc/sys/rtems/include/sys/cpuset.h: ... here. libc/sys/rtems/sys/dirent.h: Move to ... libc/sys/rtems/include/sys/dirent.h: ... here. libc/sys/rtems/sys/param.h: Move to ... libc/sys/rtems/include/sys/param.h: ... here. libc/sys/rtems/sys/syslimits.h: Move to ... libc/sys/rtems/include/sys/syslimits.h: ... here. libc/sys/rtems/sys/utime.h: Move to ... libc/sys/rtems/include/sys/utime.h: ... here.
