Should user be root to compile?

[Matt Seitz]

In docs/htmldocs/compiling.html, the example for building the
binaries shows the current user as "root". I inferred from this that
one should be the root user when building Samba. Since then, I have
been told that there is no need to build as root. Could this section
some text explaining whether compiling as root is:

-not required but recommended
-allowed but discouraged
-optional (neither recommended nor discouraged)
