It seems that the recent changes related to fnmatch breaks builds on OSX.
I tested on Travis CI, with Xcode 9.4 (clang-902).
The compiler error I get is the following:
/bin/sh ../libtool --tag=CC --mode=compile clang -DHAVE_CONFIG_H -I.
-I../src/hre -g -O2 -W -Wall -pipe -c -o fnmatch.lo fnmatch.c
libtool: compile: clang -DHAVE_CONFIG_H -I. -I../src/hre -g -O2 -W
-Wall -pipe -c fnmatch.c -o fnmatch.o
