-<userinput>CXXFLAGS=-Dstrerror=strerror</userinput>: If no macro
-strerror is defined, src/include/lib.h declares a function prototype
-for strerror which is incompatible with Glibc's /usr/include/string.h.
-By defining strerror=strerror a macro is defined which prevents the
-declaration and does not alter the meaning of strerror.
