include:
* Rework the way that poll() is detected so that it more closely
follows how the rest of the replacement functions are detected.
* Split err*() and warn*() functions into separate err.c and warn.c
files so that we can more finely isolate the objects files pulled
in by the linker. This should fix building textproc/nbsed on Solaris.
* Move more definitions from nbcompat.h into nbcompat/*.h. This makes
it more clear which NetBSD headers are expected to provide which
function declarations and macro definitions.
* Clean out nbconfig.h by moving all of the relevant definitions into
the correct nbcompat/*.h files.
* Update all of the library functions to the latest from src HEAD.
Also change the way that sources are modified when imported -- we
now include <nbcompat.h> before the first system header, include
<nbcompat/*.h> versions of headers instead of system ones where
available, and "#if 0" the sections that make no sense when being
built outside of the NetBSD source tree. This should make future
updates from src HEAD, e.g. for security updates or bug fixes,
easier.
* Move all private headers into a subdirectory and include the headers
from the private directory. This avoids any nameclashes with system
headers with the same name.
* Add mkdtemp, TAILQ_*, and statfs.
* Install a nbconfig.h file containing the discovered system information
and include it directly in nbcompat.h. Make all files use nbconfig.h
instead of config.h. Ensure that all installed headers don't include
any local header files. This makes libnbcompat more self-contained.
* Consistently use "#if HAVE_HEADER_H" instead of "#ifdef HAVE_HEADER_H"
since sometimes people put -DHAVE_HEADER_H=0 on their command lines.
