Log message:
boehm-gc: add upstream commit for libtool version

In 7.6.2, upstream intentionally but badly-advised bumped their
library major version number. In 7.6.4, they'll undo that change.
Instead of bumping twice in pkgsrc, follow their lead and get the
change in now.

See https://github.com/ivmai/bdwgc/issues/197

Bump PKGREVISION.

Log message:
Fix indentation in buildlink3.mk files.

The actual fix as been done by "pkglint -F */*/buildlink3.mk", and was
reviewed manually.

There are some .include lines that still are indented with zero spaces
although the surrounding .if is indented. This is existing practice.

Log message:
devel/boehm-gc: Fix functionality on DragonFly

Boehm-gc built on DragonFly, but it wasn't working properly.  This is
one of the major reasons lang/guile20 doesn't build.  Ths fix is proven
as it has been taken from DPorts.

Log message:
Limit the Snow Leopard build fix to just Snow Leopard, it causes runtime
failures on newer releases, shown in 'make test' failures and reported in
PR#51511.  Both 'make test' and lang/guile20 now work.  Bump PKGREVISION.

Log message:
boehm-gc: apply upstream build fix for FreeBSD/DragonflyBSD.
