What (or where) is LSTATUS ?

Commit #f523c25c12 (3rd Dec 2018) introduced this code at line 499 of 
'pango/pangowin32-fontmap.c'

    LSTATUS status;

I'm trying to build with MSVC which is giving me this error:-

    error C2065: 'LSTATUS' : undeclared identifier

I'm guessing this is a missing #include although I couldn't find out 
from MSDN where exactly LSTATUS is defined (and #including windows.h 
didn't seem to help either).  Anyone know what I need to do to get LSTATUS ?

I assume it's defined as LONG somewhere...
