Summary:                    [patch] configure fails to detect spandsp/expose.h
when not in system include path
Description: 
configure has a flag to specify the path to spandsp, if it is not installed
into the system default path.  This works well for most of the spandsp
checks (such as spandsp.h), however it fails to properly detect the
spandsp/expose.h header.  This is partly due to the fact that the autoconf
check is different (AC_CHECK_HEADER vs. AST_EXT_LIB_CHECK) and so does not
inherit the proper CFLAGS.

I saw this ticket was listed in the recent post on the Asterisk-Users
mailing list as one that is Ready For Testing.  I just tried the patch
again, against the latest 1.6.2 SVN checkout, and it still does not work:
