MPFR library allows user to conduct floating-point calculations with virtually
any (restricted by available memory only) precision with correct rounding.
Besides simple arithmetic operations like "+" and "/" the whole set of
mathematical functions is supported: sin, sqrt, pow, log, etc.
MPFR defines custom C-language type to represent floating-point number mpfr_t.
Mathematical manipulations with mpfr_t - variables are done through
assembler-look-like functions. For instance, to add two numbers x and y with
result in z special function mpfr_add(z,x,y,GMP_RNDN) should be called.
Remove WWW entries moved into port Makefiles
Commit b7f05445c00f has added WWW entries to port Makefiles based on
WWW: lines in pkg-descr files.
This commit removes the WWW: lines of moved-over URLs from these
pkg-descr files.

Add WWW entries to port Makefiles
It has been common practice to have one or more URLs at the end of the
ports' pkg-descr files, one per line and prefixed with "WWW:". These
URLs should point at a project website or other relevant resources.
Access to these URLs required processing of the pkg-descr files, and
they have often become stale over time. If more than one such URL was
present in a pkg-descr file, only the first one was tarnsfered into
the port INDEX, but for many ports only the last line did contain the
port specific URL to further information.
There have been several proposals to make a project URL available as
a macro in the ports' Makefiles, over time.
