This commit moves the inclusion of errno.h to common-defs.h and removes all other inclusions. Note that prior to this commit server.h included errno.h protected by "#ifdef HAVE_ERRNO_H". This protection was added with the Windows CE port, which is currently broken. Since no other platform needs this, I have removed the protection and the configury to support it. gdb/ 2014-08-07 Gary Benson <gbenson@redhat.com> * common/common-defs.h: Include errno.h. * defs.h: Do not include errno.h. * ada-typeprint.c: Likewise. * c-typeprint.c: Likewise. * core-regset.c: Likewise. * corefile.c: Likewise. * corelow.c: Likewise. * event-loop.c: Likewise. * f-typeprint.c: Likewise. * gnu-nat.c: Likewise. * go32-nat.c: Likewise. * i386gnu-nat.c: Likewise. * m2-typeprint.c: Likewise. * nat/linux-btrace.c: Likewise. * p-typeprint.c: Likewise. * procfs.c: Likewise. * remote-sim.c: Likewise. * rs6000-nat.c: Likewise. * target.c: Likewise. * typeprint.c: Likewise. * ui-file.c: Likewise. * valops.c: Likewise. * valprint.c: Likewise. gdb/gdbserver/ 2014-08-07 Gary Benson <gbenson@redhat.com> * configure.ac (AC_CHECK_HEADERS): Remove errno.h. * configure: Regenerate. * config.in: Likewise. * server.h: Do not include errno.h. * event-loop.c: Likewise. * hostio-errno.c: Likewise. * linux-low.c: Likewise. * remote-utils.c: Likewise. * spu-low.c: Likewise. * utils.c: Likewise. * gdbreplay.c: Unconditionally include errno.h.
