While building on Mac OS X, this code in src/callproc.c (line 1582ish):
#ifdef HAVE_NS
if (data_dir == 0)
data_dir == ns_etc_directory () != 0;
#endif
gives a warning:
cc -c -Demacs -I. -I. -I../lib -I../lib -MMD -MF
deps/callproc.d -MP -Wno-switch
-Wno-tautological-constant-out-of-range-compare -Wno-pointer-sign -g3
-O2 callproc.c
callproc.c:1582:14: warning: comparison between pointer and integer
('int' and 'const char *')
data_dir == ns_etc_directory () != 0;
~~~~~~~~ ^ ~~~~~~~~~~~~~~~~~~~
callproc.c:1582:37: warning: inequality comparison result unused
[-Wunused-comparison]
data_dir == ns_etc_directory () != 0;
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~
2 warnings generated.
Maybe s/==/=/ ?
Looks like it was added in bzr r117829 (the huge alloca() patch).

An obvious typo, fixed now. Thanks.
