provided by Andrew.

Replace leftover instances of _() by ecpg_gettext(), the latter being the
correct way to refer to the library's message catalog, instead of the one of
the program using the library.

Drop NLS support for ecpg_log(), which is a debugging instrument similar to
elog() in the backend.

We cannot support NLS in the ecpg compatlib, because that requires
ecpg_gettext, which is in ecpglib, which is not a dependency of compatlib.  It
doesn't seem worthwhile to worry about this, since the only translatable
string is "out of memory", and gettext probably won't be able to do much
without memory either.

Adjust messages to project style.

to explicitly cast the output back to char before comparing it to a char
value, else we get the wrong result for high-bit-set characters.  Found by
Rolf Jentsch.  Also, fix several places where <ctype.h> functions were being
called without casting the argument to unsigned char; this is likewise
unportable, but we keep making that mistake :-(.  These found by buildfarm
member salamander, which I will desperately miss if it ever goes belly-up.

- Free all memory in auto-prepare mode.

Created export list for ecpglib.

descriptor handling

- Really prepare statements
- Added more regression tests
- Added auto-prepare mode
- Use '$n' for positional variables, '?' is still possible via ecpg option
- Cleaned up the sources a little bit

Made sure ecpg deletes output file in case of an error.

  win32 threads.
- Fixed regression tests to run threading tests.

Use initializer string length as size for character strings.
Added ecpg_config.h file that is created via configure.

Fixed some regression test problems.

Also fixed a new Coverity report.

Implemented EXEC SQL UNDEF.
Applied first version of the regression test patch by Joachim Wieland <joe@mcknight.de>.

	- SHOW statement puts result into a variable
	- COPY TO STDOUT works

have no other gods before c.h'.  Also remove some demonstrably redundant
#include lines, mostly of <errno.h> which was added to c.h years ago.
