similar constants if they were not previously defined. All these
constants must be defined by limits.h according to C89, so we can
safely assume they are present.
Also performed an initial run through of upgrading our Copyright date to
extend to 2005 ... first run here was very simple ... change everything
where: grep 1996-2004 && the word 'Copyright' ... scanned through the
generated list with 'less' first, and after, to make sure that I only
picked up the right entries ...
division and modulo functions, to avoid problems on OS X (which fails to
trap 0 divide at all) and Windows (which traps it in some bizarre
nonstandard fashion). Standardize on 'division by zero' as the one true
spelling of this error message. Add regression tests as suggested by
Neil Conway.
from an empty text string. This makes them consistent with the de facto
behavior of type char's I/O conversion functions, and avoids generating
text values with embedded nulls, which confuse many text operators.
inputs have been converted to newstyle. This should go a long way towards
fixing our portability problems with platforms where char and short
parameters are passed differently from int-width parameters. Still
more to do for the Alpha port however.
1. Remove the char2, char4, char8 and char16 types from postgresql
2. Change references of char16 to name in the regression tests.
3. Rename the char16.sql regression test to name.sql. 4. Modify
the regression test scripts and outputs to match up.
Might require new regression.{SYSTEM} files...

The comparison routines for text and char data type give incorrect results
if the input data contains characters greater than 127. As these routines
perform the comparison using signed char variables all character codes
greater than 127 are interpreted as less than 0. These codes are used to
encode the iso8859 char sets.
The other text-like data types seem to work as expected as they use unsigned
chars in comparisons.
