[Alan Mackenzie]

branch: scratch/correct-warning-pos
commit 4e77177b063f9da8a48709aa3ef416d0ac21837b
Author: Alan Mackenzie <acm@muc.de>
Commit: Alan Mackenzie <acm@muc.de>

    Try to make scratch/correct-warning-pos build on Windows and not segfault
    
    * src/comp.c (emit_EQ): Replace calls to gcc_jit_context_new_location with
    NULLs.
    (Fcomp__init_ctxt): Remove the register_emitter call for Qsymbol_with_pos_p,
    which was causing a segfault.
