The Cygwin platform supports DOS style drive-letter paths such
as "C:\\dir", even though the preferred form is a POSIX-style
"/cygdrive/c/dir". This can be seen by doing things such as
chdir("c:") (which succeeds) followed by getcwd(NULL, 0) (which
returns the normalized "/cygdrive/c"). However, dash was trying
to perform local manipulations on the argument to 'cd' prior to
calling into libc, in order to update the state of $PWD and
friends; these manipulations were assuming that the user meant
to change to a relative subdirectory of the current location,
as in './c:', instead of honoring the drive letter. None of
the other dash builtins take a filename and manipulate it to
affect shell state (some, like 'test', take a file name, but as
stat("c:") works just fine, there is no need to normalize).
This patch has no impact outside of cygwin; on cygwin, it takes
advantage of a native function call to canonicalize any
incoming name into preferred form before updating shell state.
Pre-patch:
$ dash -c 'cd c: && echo $PWD'
dash: 1: cd: can't cd to c:
Post-patch:
$ dash -c 'cd c: && echo $PWD'
/cygdrive/c

- Solaris lacks paths.h and the various _PATH_* #defines.
Check for them in configure.ac and fall back on the
usual suspects when they are missing.
- Older Solaris lacks isblank(), and versions that have it
use a macro. Check for the declaration in configure.ac
and fall back on a naive version when missing.
- Older Solaris does not support %jd (intmax_t) in format
strings, but it does support the PRIdMAX macro from inttypes.h.
Do a configure check for PRIdMAX and use it in the code.
If it doesn't exist, define it to "lld" when sizeof(long long)
equals sizeof(intmax_t) as this is more likely to work on
older systems. Otherwise, use "jd" and hope for the best.
- Older Solaris lacks stdint.h, but inttypes.h provides the
same types and works on all platforms I've tried dash on,
so just use it instead.
- Older Solaris doesn't like it when vsnprintf() is passed
a NULL buffer (in violation of the POSIX spec, of course).
Pass a 1-byte dummy buffer instead.
- Solaris lacks tempfile and mktemp programs. Fall back on a
"good-enough" custom function in mkbuiltins.

This patch fixes the problem.

This patch adds the extra parenthesis. Thanks Peter.

Somewhere along the lines the warning when getcwd fails went missing.
This patch restores it.

AC_GNU_SOURCE always defines _GNU_SOURCE so testing it is pointless.
This patch changes it to test __GLIBC__ instead.

These days dash is expected to build with libraries other than
glibc so we need to support the old way of calling getcwd again.
Thanks to Dan McGee for reporting this bug when dash is built with
klibc.

This change updates the BSD licence to the three-clause version since
NetBSD has already done so. This makes dash GPL-compatible.
It also adds Christos Zoulas (NetBSD ash maintainer) to the COPYING file.
I've added "copyright by Herbert Xu" to most files.
Finally all CVS IDs and inclusion of sys/cdefs.h have been removed.
The latter is needed for support of klibc.
