__attribute__() marker so that gcc can validate the format string against
the actual arguments, get rid of overcomplicated and unsafe usage in
base_yyerror().
In the backend, I changed only a handful of exemplary or important-looking
instances to make use of the plural support; there is probably more work
there. For the rest of the source, this should cover all relevant cases.
noise words for the last twelve years, for compatibility with Berkeley-era
output formatting of the special INVALID values for those datatypes.
Considering that the datatypes themselves have been deprecated for awhile,
this is taking backwards compatibility a little far. Per gripe from Josh
Berkus.
kwlist.h, to avoid having to link the backend object file into other programs
like pg_dump. We can now simply symlink a single source file from the backend
(kwlookup.c, containing the shared routine ScanKeywordLookup) and compile it
locally, which is a lot cleaner.
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.
preprocessor and the library. This is useful for a number of reasons:
* The preprocessor and the library are in some cases installed in separate
packages and used by different classes of users.
* The library MO files need a different versioning scheme to account for the
soname.
* The makefiles are simpler, more robust, and easier to maintain this way.
(NLS web site was prone to break everytime a build rule changes.)
* Translators might choose to focus on the ecpglib, because that is more
user-facing.
* There was virtually no overlap, so nothing is lost.
