Let 'pear build' work on windows for building pecl extensions.

A few notes:
Currently only supports release builds, and of course, requires msdev!
pecl packages must have package.xml and xxx.dsp files for this to work
the package name in package.xml must match the name of the dsp file, so
package iisfunc must have dsp iisfunc.dsp
