Subject: Some guile-2.0 asyncs functions do not link correctly
Date: Sun, 1 Jun 2014 17:54:48 +0100

guile-2.0's scm_c_call_with_blocked_asyncs,
scm_c_call_with_unblocked_asyncs, scm_dynwind_block_asyncs and
scm_dynwind_unblock_asyncs will not link for me using 32-bit
ubuntu-14.04 (gcc-4.8.2/guile-2.0.9) or 32-bit slackware-14.1
(gcc-4.9.0/guile-2.0.11).  I do not have a machine to test a 64-bit
system at present.

The issue appears to be that this part of the API is not exported, even
though these functions are documented and appear intended to be called
by user code.

A patch, against guile-2.0.11, is below, dealing with this.
