Log message:
Simply and speed up buildlink3.mk files and processing.
This changes the buildlink3.mk files to use an include guard for the
recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS,
BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new
variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of
enter/exit marker, which can be used to reconstruct the tree and
to determine first level includes. Avoiding := for large variables
(BUILDLINK_ORDER) speeds up parse time as += has linear complexity.
The include guard reduces system time by avoiding reading files over and
over again. For complex packages this reduces both %user and %sys time to
half of the former time.

Log message:
Restore a fixed version of patch-ah.  While -R was in the string, it
was there because guile was built against gmp etc. from /usr/pkg, not
present to let programs find -lguile.  Therefore, add in rpath for
$(libdir) when we add in -L for libdir.

This looks ok to me, but I will be away AFK most of the day, so feel
free to remove the line in distinfo and re-commit if this turns out to
be bad.

Log message:
Remove patch to add -Wl,-R to guile-config link.  I had borked it when
merging to the new guile-config code, and it turns out not to be
necessary since there is some other mechanism to add rpath.  Arguably
it should still be added, as the later rpath might only be there for
dependencies.  (Plus, depending programs should use pkg-config
instead.)

Log message:
Update to 1.8.6.  Adjust patch-ah slightly for new upstream code.
Delete patch-aa as the whole lt_preloaded_symbols bit is gone upstream.

Changes in 1.8.6 (since 1.8.5)

* New features (see the manual for details)

** New convenience function `scm_c_symbol_length ()'

** Single stepping through code from Emacs

When you use GDS to evaluate Scheme code from Emacs, you can now use
`C-u' to indicate that you want to single step through that code. See
`Evaluating Scheme Code' in the manual for more details.

** New "guile(1)" man page!

* Changes to the distribution

** Automake's `AM_MAINTAINER_MODE' is no longer used

Thus, the `--enable-maintainer-mode' configure option is no longer
available: Guile is now always configured in "maintainer mode".

** `ChangeLog' files are no longer updated

Instead, changes are detailed in the version control system's logs.  See
the top-level `ChangeLog' files for details.

* Bugs fixed

** `symbol->string' now returns a read-only string, as per R5RS
** Fix incorrect handling of the FLAGS argument of `fold-matches'
** `guile-config link' now prints `-L$libdir' before `-lguile'
** Fix memory corruption involving GOOPS' `class-redefinition'
** Fix possible deadlock in `mutex-lock'
** Fix build issue on Tru64 and ia64-hp-hpux11.23 (`SCM_UNPACK' macro)
** Fix build issue on mips, mipsel, powerpc and ia64 (stack direction)
** Fix build issue on hppa2.0w-hp-hpux11.11 (`dirent64' and `readdir64_r')
** Fix build issue on i386-unknown-freebsd7.0 ("break strict-aliasing \ 
rules")
** Fix misleading output from `(help rationalize)'
** Fix build failure on Debian hppa architecture (bad stack growth detection)
** Fix `gcd' when called with a single, negative argument.
** Fix `Stack overflow' errors seen when building on some platforms
** Fix bug when `scm_with_guile ()' was called several times from the
   same thread
** The handler of SRFI-34 `with-exception-handler' is now invoked in the
   dynamic environment of the call to `raise'
** Fix potential deadlock in `make-struct'
** Fix compilation problem with libltdl from Libtool 2.2.x
** Fix sloppy bound checking in `string-{ref,set!}' with the empty string
