[2.2.1] lib/xmlparse.c compilation error (getentropy) on macOS #52
Description
I'm getting a compilation error with expat version 2.2.1 on macOS (both with clang and gcc)
Clang error:
/bin/sh ./libtool --verbose --mode=compile clang -I./lib -I. -g -O2 -Wall -Wmissing-prototypes -Wstrict-prototypes -fexceptions -fno-strict-aliasing -DHAVE_EXPAT_CONFIG_H -o lib/xmlparse.lo -c lib/xmlparse.c

Compiling and installing libbsd didn't help.
2.2.0 compiles w/o any problems (which makes sense, given the 2.2.1 Changelog)
Building 2.2.1 with CMake somehow finishes successfully, however, the resulting dylib (dynamic library) has a different compatibility version than the one built using configure/make, which causes problems with binaries that depend on expat. Another issue?
