bug#31845: 27.0.50; Error building master on MacOS

[John Mastro]

Hello,

I get the following warnings and error when building master at 3e7dff8
on MacOS 10.13.5 (High Sierra).

macfont.m:911:27: warning: passing 'CFStringRef' (aka 'const struct
__CFString *')
      to parameter of type 'void *' discards qualifiers
      [-Wincompatible-pointer-types-discards-qualifiers]

I just tried again after seeing Paul Eggert pushed a related commit
(850c0c1). The two warnings are gone but this error remains:

macfont.m:911:56: error: use of undeclared identifier 'traits'
                  Fcons (make_mint_ptr ((void *) name), make_number (traits)));
                                                                     ^
1 error generated.
make[2]: *** [macfont.o] Error 1
make[1]: *** [src] Error 2

Thanks

                                                                     ^

This is a typo from commit 6c04c848. Replacing traits with sym_traits
should fix it.

Sorry about that, and thanks for letting me know. Closing the correct bug number 
(31845) now.
