Description:
------------
Calls to the Win32 API MessageBox block automated testing. When the automation 
is spawned by a timed script, that script does not have access to the UI to 
close these messages.

3 places where MessageBox is called:

Zend/zend_ini_parser.y:179 - instead of printing an INI parse error to stderr, 
*always* when PHP_WIN32 is defined. This means that the test suite does not 
catch the error on Windows machines (example parse error directive `php -n -d 
foo="a=href"`) and execution of automated tests is blocked until a user can 
click through.
 - example 

main/main.c:984 - in addition to other logging, but only if 
display_startup_errors is true and the error type is either E_CORE_WARNING or 
E_CORE_ERROR.
 - since display_startup_errors is set to true by the testing suite (and is 
required for many tests to pass), I cannot disable it. Perhaps a new ini 
directive should be created instead of having this one overloaded?

sapi/cgi/cgi_main.c:1768 - only when PHP_DEBUG is defined. I don't have a big 
problem with this, since it is debug code, but perhaps it too could be governed 
by an ini directive.

Test script:
---------------
pass a deliberately-defective ini directive:

`php -n -d a=b=c -v`


Expected result:
----------------
--STDERR--
php: syntax error, unexpected '=' in Unknown on line 7
