Description:
------------
TSRM/tsrm_virtual_cwd.c uses the same name for a global variable as well as for arguments to a function (when #ifndef ZTS).

#ifdef ZTS
ts_rsrc_id cwd_globals_id;
#else
virtual_cwd_globals cwd_globals;
#endif


static void cwd_globals_ctor(virtual_cwd_globals *cwd_globals TSRMLS_DC) /* {{{ */

static void cwd_globals_dtor(virtual_cwd_globals *cwd_globals TSRMLS_DC) /* {{{ */


Reproduce code:
---------------
The following patch avoids the name clash:

Expected result:
----------------
Disambiguity.
