stdint.h was added to common-defs.h some months ago and should no longer be included directly by any file. gdb_assert.h was added to common-defs.h nearly a year ago, but three includes have crept in since then. This commit removes all such redundant include directives. gdb/ChangeLog: * common/buffer.c (stdint.h): Do not include. * common/print-utils.c (stdint.h): Likewise. * compile/compile-c-symbols.c (gdb_assert.h): Likewise. * compile/compile-c-types.c (gdb_assert.h): Likewise. * ft32-tdep.c (gdb_assert.h): Likewise. * guile/scm-utils.c (stdint.h): Likewise. * i386-linux-tdep.c (stdint.h): Likewise. * i386-tdep.c (stdint.h): Likewise. * nat/linux-btrace.c (stdint.h): Likewise. * nat/linux-btrace.h (stdint.h): Likewise. * nat/linux-ptrace.c (stdint.h): Likewise. * nat/mips-linux-watch.h (stdint.h): Likewise. * ppc-linux-nat.c (stdint.h): Likewise. * python/python-internal.h (stdint.h): Likewise. * stub-termcap.c (stdlib.h): Likewise. * target/target.h (stdint.h): Likewise. * xtensa-linux-nat.c (stdint.h): Likewise. gdb/gdbserver/ChangeLog: * linux-i386-ipa.c (stdint.h): Do not include. * lynx-i386-low.c (stdint.h): Likewise. * lynx-ppc-low.c (stdint.h): Likewise. * mem-break.c (stdint.h): Likewise. * thread-db.c (stdint.h): Likewise. * tracepoint.c (stdint.h): Likewise. * win32-low.c (stdint.h): Likewise.
