Implements the Distutils 'config' command, a (mostly) empty command class
that exists mainly to be sub-classed by specific module distributions and
applications. The idea is that while every "config" command is different,
at least they're all named the same, and users always see "config" in the
list of standard commands. Also, this is a good place to put common
configure-like tasks: "try to compile this C code", or "figure out where
this header file lives".

the preprocessor, and return true if any line of the output matches
'pattern'. 'pattern' should either be a compiled regex object or a
string containing a regex. If both 'body' and 'headers' are None,
preprocesses an empty file -- which can be useful to determine the
symbols the preprocessor and compiler set by default.

source file that refers to 'func', and compiles and links it.
If everything succeeds, returns true; otherwise returns false.
The constructed source file starts out by including the header
files listed in 'headers'. If 'decl' is true, it then declares
'func' (as "int func()"); you probably shouldn't supply 'headers'
and set 'decl' true in the same call, or you might get errors about
a conflicting declarations for 'func'. Finally, the constructed
'main()' function either references 'func' or (if 'call' is true)
calls it. 'libraries' and 'library_dirs' are used when
linking.

without actually checking that any particular symbols are provided
by it. 'headers' will be used in constructing the source file to
be compiled, but the only effect of this is to check if all the
header files listed are available. Any libraries listed in
'other_libraries' will be included in the link, in case 'library'
has symbols that depend on other libraries.
