This feature has been added to the latest Arduino source code, although is not yet in a released version (see https://github.com/arduino/Arduino/commit/a2235e3cdc3856cbeba7de84e81bfd914b3ebaea).

It's planned to be included in the next major Arduino IDE release (version 1.0) which is currently planned for release at the end of October 2011. The current release candidate has this fix (as of October 25, 2011).

To enable compiler warnings from within the Arduino IDE, open File | Preferences then tick Show verbose output during: compilation and/or Show verbose output during: upload.
