Check return values of read() and write().  Avoid some unsigned
comparisons.  Cast a ptrdiff_t value to int for use with %d in a

[ghudson@mit.edu: rewrap long lines; fix one more warning; commit
message]

In a static build, linking dbtest could fail on platforms where libdb2
depends on krb5support (platforms without a native mkstemp).  Reported
by Gilles Espinasse <g.esp@free.fr>.

ticket: 7651

Provide default values in pre.in for PROG_LIBPATH, PROG_RPATH,
SHLIB_DIRS, SHLIB_RDIRS, and STOBJLISTS so that they don't have to be
specified in the common case.  Rename KRB5_RUN_ENV and KRB5_RUN_VARS
to RUN_SETUP (already the most commonly used name) and RUN_VARS.  Make
sure to use DEFINES for local defines (not DEFS).  Remove some other
unnecessary makefile content.

The test suite for libdb2 uses /bin as a source of filenames and
contents for insertion into databases.  Fedora 17 (and possibly other
OSes) have /bin symlinked to /usr/bin, which can vastly increase the
number of files found, exceeding some limits of the test databases.
Truncate this list of files at 100 to prevent this problem.

verbiage in Makefile.in files.  For correctness of output, every
Makefile.in mydir= definition is changed to use $(S) instead of /.

The libdb2 test suite would fail if /bin/csh was not present.  The
tests did not execute /bin/csh - but used the contents as data to put
into the test database.  Iterate over a few "known" files until one is found
that could be used for it... Tests for /bin/csh, /bin/cat, /usr/bin/cat, 
/bin/ls, /usr/bin/ls.  If none of these exist - then fail.

Move automatically-generated dependencies into separate files in the
source tree, and take the data out of Makefile.in.

Keep the "make depend" rules for stripping out the dependencies from
Makefile.in, in case some optional directories were missed, but
everything that builds on my UNIX build has been converted.
(Converting a directory just requires creating an empty "deps" file so
that config.status can build the makefile, and then later running
"make depend" in that directory to get the correct content for it.)

Change configure scripts to incorporate the "deps" file when building
each Makefile.  This change requires the existence of a file "deps" in
each source directory where we build a makefile, even if there are no
sources for which to compute dependencies; a switch to GNU make would
let us conditionalize that, but we can assess that later.

Update dependencies for the generate Makefile itself to list the deps
file.

This will also require some minor tweaking of the Windows build, to
make it incorporate the new deps file.
