AC_SUBST that messed up the diversions and thus the configure output.

Found while testing against a full checkout. Peter

Recode test for equality of source and build directory using 'test -ef',
because even using pwd you might not get equal strings.  Thanks, QNX.

When no suitable YACC is configured, supply useful informational messages
to users.  (Same way flex has been handled for a while.)

has problems when linking with both.

eliminates a raft of portability issues, including whether sys_nerr
exists, whether the platform has any valid negative errnos, etc.  The
downside is minimal: errno shouldn't ever contain an invalid value anyway,
and if it does, reasonably modern versions of strerror will not choke.
This rangecheck idea seemed good at the time, but it's clearly a net loss,
and I apologize to all concerned for having ever put it in.

optimized away completely.

but take it as 'int *' instead.

Add real test for whether ld -R works on Unixware.

Rename --enable-uniconv to --enable-unicode-conversion.

Install shlibs mode 755 by default, since 644 causes gratuitous complaints
from ldd et al. on some systems.

standard installation layout it should be possible to build the HTML
and print documentation without additional manual setup.

included, and then include <strings.h> if so.  Several systems already
needed <strings.h> anyway.  Some new systems that claim to conform to the
Unix 9x "standard" do not declare str[n]casemp() in string.h, and C99
compilers will not like that.

waiting for input.  From Pete Forman <gsez020@kryten.bedford.waii.com>.

source).  Adjust resultmap accordingly and fix some other regexps.

messed up and we end up with the comments from included files in the output
"configure".

flags for Solaris.  The test itself is straight from libtool.

source directory.  This involves mostly makefiles using $(srcdir) when they
might have used ".".  (Regression tests don't work with this, yet.)

Sort out usage of CPPFLAGS, CFLAGS (and CXXFLAGS).  Add "override" keyword
in most places, to preserve necessary flags even when the user overrode the
flags.

Update the installation instructions (formerly misnamed "FAQ"), add configure
checks for some headers rather than having users copy stubs manually (ugh!).
Use Autoconf check for exe extension.  This also avoids inheriting the value
of $(X) from the environment.

add --without-tk option to disable Tk.  We don't need the AC_PATH_XTRA
test because tkConfig.sh already contains all the information about how to
compile and link with X.  Also make sure that libpq is up to date for
libpgtcl.  Remove executable bits from pgaccess.sh, but add it to pgaccess.

that's actually useful, robust, consistent.

Better plan to generate aclocal.m4 as well: use m4 include directives,
rather than cat.

incarnations (I hope). When an acceptable flex version is not found, print
instructive error messages from both configure and the makefiles, so that
users can continue building anyway.

the harm potential outweighs the possible benefits.

argument, change the order of tests for the third argument to be safe
against missing prototypes, and make it fail hard if none of the
combinations succeed.

Interfaced a lot of the custom tests to the config.cache, in the process
made them separate macros and grouped them out into files. Made naming
adjustments.

Removed a couple of useless/unused configure tests.

Disabled C++ by default. C++ is no more special than Perl, Python, and Tcl.
And it breaks equally often. :(

that now functions as a wrapper around the MakeMaker stuff. It might
even behave sensically when we have separate build dirs. Same for plperl,
which of course still doesn't work very well. Made sure that plperl
respects the choice of --libdir.

Added --with-python to automatically build and install the Python interface.
Works similarly to the Perl5 stuff.

Moved the burden of the distclean targets lower down into the source tree.
Eventually, each make file should have its own.

Added automatic remaking of makefiles and configure. Currently only for the
top-level because of a bug(?) in Autoconf. Use GNU `missing' to work around
missing autoconf and aclocal. Start factoring out macros into their own
config/*.m4 files to increase readability and organization.

configuration helper things into config/ dir. Adjusted some relative paths
in makefiles.
