To build this software you need a C++ compiler that supports a
reasonably modern version of C++.  In particular the compiler must
support nested types and process temporary variables according to the
ANSI Reference Manual (the ARM).

If such a compiler is in a non-standard location, you can specify its
location in several ways:

    o set the environment variable CXX
    o create a config.local or config.site file that includes a
      definition for CXX
    o supply it on the command line using -with-CXX=<pathname>

If you are trying to use GNU gcc, but you do not have version 2.6.1
or newer, then you must update your compiler (and probably libg++ as
well) before you can compile this software.  Consult the documentation
for information about obtaining an up-to-date version of gcc.

		file formats in section 5) or "sysv" for System V-style
		organization (e.g. file formats in section 4).

<formatting>    is either "nroff" to force installation of formatted
                materials (using nroff) or "source" to get the nroff
		source installed.

<compression>   is either the name of a program to compress the manual
                pages (gipz, compress, pack) or "cat" for uncompressed data.

<suffix>        is either the file suffix to convert installed pages to
                (e.g. 0.gz for gzip-compressed pages under BSD) or "strip"
		to force the normal ".4f" suffix to be converted to ".4"
		(or ".5" if using the BSD organization).  If no -<suffix>
		is specified then filenames are not converted when they
		are installed.

Common schemes are:

bsd-nroff-gzip-0.gz	compressed formatted pages for BSD 
bsd-source-cat		nroff source w/ BSD organization
sysv-source-cat-strip	nroff source for SysV w/o .4f suffix
