Log message:
Drop superfluous PKG_DESTDIR_SUPPORT, "user-destdir" is default these days.

Log message:
Do not build and install flex.pdf, too many dependencies for such
a low-level package. Bump PKGREVISION.

Log message:
It seems pdftex is also needed, no idea why this wasn't detected earlier.

Log message:
Update to 2.5.36. Add build dependencies on gtexinfo and two tex
packages needed to build pdf documentation, since there is no
configure option to disable it that I can see. If this leads to
problems, we'll have to disable it with a patch.

* version 2.5.36

** various portability fixes that quiet compiler warnings on 64-bit
   hosts

** various manual fixes, including correcting the name of a %option and
   updating some simple examples to use ANSI C syntax

** various bug fixes that prevent certain error conditions from
   persisting when they should not persist

** improvements to the test suite so it behaves better when linking
   compiled files

** new translations from the translation project: ca, da, es, fi, fr,
   ga, ko, pt_br, ro, ru, sv, tr, zh_cn

** the flex distribution is now built with automake 1.10.1 and automake
   2.61

Log message:
recursive bump from gettext-lib shlib bump.

Log message:
bumping pkgrevision ought to have gone in with addition of patches/patch-ad

Log message:
The comment above the code patch in the new patch file says:
"This is a Hail Mary situation. It seems to work."
It doesn't reliably on NetBSD-5 or -current; namely, it makes flex
spit out a "Broken pipe" when presented with an input file on stdin.

Finding the problem area and suggesting a workaround kudos mlelstv.
There are better ways to fix it properly, which will be employed
in Due Time.

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.

turn on linux source compatibility for AIX - flex dumps core otherwise
