On some recent Windows systems, ext\pcre\tests\locales.phpt fails,
because 'pt_PT' is accepted by `setlocale()`, but not properly
supported by the ctype functions, which are used internally by PCRE2 to
build the localized character tables.
Since there appears to be no way to properly check whether a given
locale is fully supported, but we want to minimize BC impact, we filter
out typical Unix locale names, except for a few cases which have
already been properly supported on Windows. This way code like
setlocale(LC_ALL, 'de_DE.UTF-8', 'de_DE', 'German_Germany.1252');
should work like on older Windows systems.
It should be noted that the locale names causing trouble are not (yet)
documented as valid names anyway, see
<https://docs.microsoft.com/en-us/cpp/c-runtime-library/locale-names-languages-and-country-region-strings?view=vs-2019>.
If we perform a class fetch that is not marked as exception safe,
convert exceptions thrown by autoloaders into a fatal error.
Ideally fetching the interfaces would be exception safe, but as it
isn't right now, we must abort at this point.
`curl_version()`[1] (of ext/curl) makes `curl_version_info()`[2] (of
libcurl) available to PHP userland. The latter requires to pass an
`age` argument which usually is `CURLVERSION_NOW`, so that the
information returned by the runtime matches the declarations used
during compile time. For C programs it is simply necessary to pass
this information, and in rare occasions it might make sense to pass
something else than `CURLVERSION_NOW`. curl.h notes:
| The 'CURLVERSION_NOW' is the symbolic name meant to be used by
| basically all programs ever that want to get version information.
For the PHP binding, using a newer `age` than available at compile time
will neither provide the PHP program more information, nor would using
an older `age` have tangible benefits.
We therefore deprecate the useless `$version` parameter, and if it is
passed nonetheless, we use `CURLVERSION_NOW` instead of the supplied
value, and raise a warning.
