- src/rbox.c (main): Avoid problems of evaluation order when
pre-incrementing arguments of strtod
- src/io.c (qh_produce_output), src/stat.c (qh_initstatistics): Use %lu
instead of %d in the format string for arguments of type size_t
- html/qhull.man, html/rbox.man: Fix several syntax, macros, and hyphen
problems in man pages
- The Autotools files have been generated with modern version of autoconf (2.63),
automake/aclocal (1.10.2), and libtool (2.2.6)
- Some character issues in the man pages are fixed
