bug#17646: emacs-devel-24.4.50.117036 no longer builds on DragonFly (patch)

[John Marino]

For many months DragonFly BSD users have enjoyed building EMACS without
patches.  Recently the builds broke:

> In file included from gnutls.c:23:0:
> process.h:216:33: error: unknown type name 'sigset_t'
> process.h:217:44: error: expected ')' before 'const'
> gmake[2]: *** [gnutls.o] Error 1
> gmake[2]: *** Waiting for unfinished jobs....

> gmake[1]: Leaving directory 
> `/wrkdirs/editors/emacs-devel/work/emacs-24.4.50.117036'
> ===> Compilation failed unexpectedly.

The following patch will let the build finish, but obviously it's not
suitable for inclusion:

=============================

Can somebody convert my patch into the proper fix and commit it?

Thanks,
John
