Subject: Expand the variables in PHP_EXPAND_BUILD_VARS.
X-Git-Tag: php-4.3.0dev-ZendEngine2-Preview1~1186
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=350de12bc24472ccf20ff9a8b39a6da0185c070d;p=php

Expand the variables in PHP_EXPAND_BUILD_VARS.

Make HAVE_ICONV/HAVE_LIBICONV available through the more
fine-grained approach using a single include file per
directive.  This will significantly reduce the price of
full dependencies for developers, because basically each
file today includes php.h which includes php_config.h.

If PHP_ATOM_INC is defined, these include files can be used.

For all PHP_DEFINEs, empty files are created upon configure start.
