Simon Marchi 577d2167bb gdb: move clearing of tp->pending_follow to follow_fork_inferior
A following patch will change targets so that when they detach an
inferior, they also detach any pending fork children this inferior may
have.  While doing this, I hit a case where we couldn't differentiate
two cases, where in one we should detach the fork detach but not in the
other.

Suppose we continue past a fork with "follow-fork-mode == child" &&
"detach-on-fork on".  follow_fork_inferior calls target_detach to detach
the parent.  In that case the target should not detach the fork
child, as we'll continue debugging the child.  As of now, the
tp->pending_follow field of the thread who called fork still contains
the details about the fork.

Then, suppose we run to a fork catchpoint and the user types "detach".
In that case, the target should detach the fork child in addition to the
parent.  In that case as well, the tp->pending_follow field contains
the details about the fork.

To allow targets to differentiate the two cases, clear
tp->pending_follow a bit earlier, when following a fork.  Targets will
then see that tp->pending_follow contains TARGET_WAITKIND_SPURIOUS, and
won't detach the fork child.

As of this patch, no behavior changes are expected.

		   README for GNU development tools

This directory contains various GNU compilers, assemblers, linkers, 
debuggers, etc., plus their support routines, definitions, and documentation.

If you are receiving this as part of a GDB release, see the file gdb/README.
If with a binutils release, see binutils/README;  if with a libg++ release,
see libg++/README, etc.  That'll give you info about this
package -- supported targets, how to use it, how to report bugs, etc.

It is now possible to automatically configure and build a variety of
tools with one command.  To build all of the tools contained herein,
run the ``configure'' script here, e.g.:

	./configure 
	make

To install them (by default in /usr/local/bin, /usr/local/lib, etc),
then do:
	make install

(If the configure script can't determine your type of computer, give it
the name as an argument, for instance ``./configure sun4''.  You can
use the script ``config.sub'' to test whether a name is recognized; if
it is, config.sub translates it to a triplet specifying CPU, vendor,
and OS.)

If you have more than one compiler on your system, it is often best to
explicitly set CC in the environment before running configure, and to
also set CC when running make.  For example (assuming sh/bash/ksh):

	CC=gcc ./configure
	make

A similar example using csh:

	setenv CC gcc
	./configure
	make

Much of the code and documentation enclosed is copyright by
the Free Software Foundation, Inc.  See the file COPYING or
COPYING.LIB in the various directories, for a description of the
GNU General Public License terms under which you can copy the files.

REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info
on where and how to report problems.
