- Unbreak the build on 9.x (against GCC 4.2): it was failing due to -ansi option passed by default, which does not allow C++-style comments in C source code (Clang is more forgiving):
/usr/local/include/clamav.h:170: error: expected identifier or '(' before '/' token /usr/local/include/clamav.h:170: error: stray '#' in program
- Really respect CFLAGS by fixing configure script
- Do not hardcode DISTVERSION in MASTER_SITES
- Do not install COPYING file as part of portdocs: it's installed via LICENSE_FILE already
- Convert the port to use option helpers, fix a typo (VIRUSTAGSC -> VIRUSTAG_DESC), wrap overly long lines
- Augment port description text while I'm at it
