PDO include paths can be simplified and synced as done in other
extensions: either the project root directory or the phpincludedir (for
the system installation). The 'ext' include is automatically appended
when doing phpize build. In php-src it is only present on Windows build.
The PHP_CHECK_PDO_INCLUDES is left intact working as before and checks
if PDO headers are found.
This syncs build system gaps of some extensions' definitions being
defined on Windows and some on *nix. These are not used anywhere and are
only defined in some build system and not the other:
* HAVE_INTL (was present only on Windows)
* HAVE_PDO_DBLIB (was present only on Autotools)
* HAVE_PDO_FIREBIRD (was present only on Autotools)
* HAVE_TOKENIZER (was present only on Windows)
Some editors utilizing .editorconfig automatically trim whitespaces. For
convenience this patch removes whitespaces in certain build files:
- ext/*/config*.m4
- configure.ac
- acinclude.m4
modern versions in the same build chain. There are
simply too many broken things in 2.13 to make it work.
Cache handling is broken as well which is why I need
to revert the pdo_inc_path cache fix as well.
trunk is now 2.60+ only and I'll work on cleaning out
all the legacy cruft from there.
Enabled PDO and PDO_SQLITE by default.
Fixup PDO header detection so that it searches in the correct order, and
correctly picks up the headers when building from outside of the source
tree.
TODO: make pdo_XXX auto-enable when XXX is enabled. Volunteers welcome.
