This patch moves the gdb/gnulib subdirectory to the top level. It adjusts the top-level build system to build gnulib when necessary, and changes gdb to use this. However, gdbserver still builds its own copy of gnulib, just from the new source location. A small hack was needed to ensure that gnulib is only built when gdb is enabled. The Makefile only provides an ordering -- the directory must be mentioned in configdirs to actually be compiled at all. Most of the patch is just a "git mv" of gnulib, though a few minor path adjustments were needed in some files there. Tested by the buildbot.

PATH_MAX is not defined on systems which have no limit on filename length,

This file does *not* define PATH_MAX always. Programs that use this file

- Either with a package-wide handling, or with a per-file handling,

- Either through a

#ifdef PATH_MAX

|
or through a fallback like
|
|
#ifndef PATH_MAX
|

# define PATH_MAX 8192

or through a fallback like
