Description:
------------
Using MipsPro CC for compling php produces this kind of error.
cc-1133 cc: ERROR File = /mnt/MIPS/php5-200403131830/ext/simplexml/simplexml.c, Line = 1282
  Expression must be a modifiable lvalue.

                (php_libxml_node_object *)sxe->document = NULL;

<citat>
* gcc allows the use of casts as lvalues. For example:
          void *foo;
          (char*)foo += 5;
       When using MIPSpro compilers you cannot assign to casts:
          void *foo;
          foo = (char*)foo + 5;
</citat>

So 
((php_libxml_node_object *)(sxe))->document
or

php_libxml_node_object * sxe_foobar  = sxe;
sxe_foobar->document = NULL;

must be using for a proper cast.

Btw. the changelog for the upcomming GCC 3.4 mentioned this as deprecated.

Joerg
