Thank you for the report. Technically, we could fix it by adding more ifdefs, but I think it would not be worthwhile to accommodate this use case. To resolve that, I suggest to install libpcre. Otherwise, when building without PCRE support, please either avoid the configure-time --enable-gcc-warnings option or invoke make with the "WERROR_CFLAGS=" option to suppress -Werror.
