The problem here is that if a thread other than gdb's main thread
gets a SIGCHLD (it's an asynchronous signal so the kernel will
essentially pick a random thread) then gdb will hang if it is
in sigsuspend when the SIGCHLD is delivered. The other thread
will see the signal and the sigsuspend won't "wake up".
Guile and libgc should be blocking SIGCHLD in their threads,
but we need to work with Guile 2.0 and libgc 7.4.
The problem first shows up in libgc 7.4 because it is the first
release that enables multiple marker threads by default.

PR 17185 describes a problem with using gdb+guile with libgc 7.4.0.
The symptom is a hang in sigsuspend.
[The thread referenced in the PR has the details.]
It's not clear what the right fix is, or even where the bug is yet.
This patch applies the same workaround Guile has applied.
There is no functionality or real performance loss with this,
and Guile has been using it for awhile.

This commit wraps calls to the demangler with a segmentation fault
handler. The first time a segmentation fault is caught a core file
is generated and the user is prompted to file a bug and offered the
choice to exit or to continue their GDB session. A maintainence
option is provided to allow the user to disable the crash handler
if required.

gdb already unconditionally includes stddef.h in many places.
I think there is no reason to check for its existence.
Also, Zack Weinberg's header file survey agrees:
http://hacks.owlfolio.org/header-survey/

It also removes a redundant inclusion that I noticed in defs.h.

My grepping around showed that HAVE_MULTIPLE_PROC_FDS is only ever
mentioned in a comment in configure.ac. Since the macro is long dead,
let's remove the last mention.

* configure: Rebuild.
* configure.ac: Remove mentions of HAVE_MULTIPLE_PROC_FDS.
Now that the configury needed for the "common" and "target"
directories is in common.m4, some code in gdb's configure.ac is
redundant.
I ran this script after making an "ID" file using mkid:
sed -n 's/^.*\(HAVE_[A-Z0-9_]*\).*$/\1/p' config.in |
while read x; do
echo ===== $x
gid $x | egrep -v '^(testsuite|gnulib|common|target|gdbserver)/'
done
This finds all the spots using HAVE_ defines, and, more importantly,
makes it clear which defines aren't used in the main parts of gdb.
From this I came up with this patch to remove all the unused bits.
There are a few that are subtly used -- for example the configure
script sometimes checks internal configure cache variables, meaning
some checks cannot be removed.

This simplifies the .gdbinit filename selection logic.
We have a GDBINIT_FILENAME define that supposedly configurations would
override, but none do so. Instead, the only configuration that wants
a different file name instead of ".gdbinit", djgpp, does a strcpy over
the gdbinit global array. This means the array needs to be sized, and
the code that does that is doing the usual
'PATH_MAX/FILENAME_MAX/fallback constant/etc.' mess.
Instead of all that, it's much simpler to have configure specificy the
.gdbinit filename. As bonus, we can then make the "gdbinit" global
array const.

../../src/gdb/common/filestuff.c:38:24: fatal error: sys/socket.h: No such file or directory
There are no sockets on djgpp. This #ifdef's out the bits in the file
that use sockets, depending on whether winsock or sys/socket.h is
available.
As alternative approach, given ser-tcp.c, ser-pipe.c, etc. are split
into separate files, and which to use is selected by configure.ac:
dnl Figure out which of the many generic ser-*.c files the _host_ supports.
SER_HARDWIRE="ser-base.o ser-unix.o ser-pipe.o ser-tcp.o"
case ${host} in
*go32* ) SER_HARDWIRE=ser-go32.o ;;
*djgpp* ) SER_HARDWIRE=ser-go32.o ;;
*mingw32*) SER_HARDWIRE="ser-base.o ser-tcp.o ser-mingw.o" ;;
esac
AC_SUBST(SER_HARDWIRE)
... I considered splitting filestuff.c similarly. But I quickly gave
up on the idea, as it looked like a lot more complication over this
approach, for no real gain. Plus, there are uses of these functions
outside the ser*.c framework.
