Log message:
Explicitly check for libnsl and libsocket as required by Solaris.
Based on patches from Aleksey Cheusov.

Log message:
Include nbcompat/types.h early to make sure that uintX_t are defined.
Reported by Aleksey Cheusov and Joern Clausen in PR 39738.

Log message:
pkg_install-20081010:
Add optional bdb. Make it included by default for standalone builds.

Log message:
Mac OS X doesn't define uintXX_t in sys/types.h, so explicitly pull in
inttypes.h if present. Make md5.h, sha1.h and sha2.h self contained by
including nbcompat/types.h. Problem reported by Greg Troxel.

Log message:
Check for existance of sysexits.h and regen config.h.in.

Log message:
libnbcompat-20080922:
- DESTDIR support
- Add check for inttypes.h and sys/socket.h
- Provide compatibility fallback for netdb.h and the RFC2553 API
(getaddrinfo), supoprting IPv4 only. Code from OpenSSH.
- Use normal autoconf checks for fixed size bit types. Stop using the
older BSD types (u_intXX_t) in libnbcompat.
- Add implementation of shquote (from NetBSD).
- Fix a buglet in the getenv/setenv/unsetenv detection.
- Fix a buglet in the mkdtemp/mkstemp detection.

Log message:
Determine both for setmode.c and pwcache.c if any of the functions is
provided by the system and if one is lacking use the file. Don't short
cut the list as before and do a second iteration, it is just confusing.

This breaks the regression introduced by the last commit on OS X.

Log message:
libnbcompat-20080908:
- declare endpwent and endgrent if system headers are missing them
- check for existance of statfs.f_flags before using it
- drop a bunch of redundant function checks

Based on the work of Timothy Larson.

Log message:
Don't mess with PKG_* as it is not required to build bootstrap
components and it interferes with normal builds.

Log message:
Make style more consistent.
