source: configure @ b0a89cc

Last change on this file since b0a89cc was b0a89cc, checked in by Wilmer van der Gaast <wilmer@…>, at 2010-08-27T08:48:18Z

Use nifty gcc -MD feature to automatically track .h dependencies of all C
files, this finally gives proper dependencies, which means the end of
getting broken binaries around headerfile changes, etc.

Sure, this may not work on obscurux with superawesomeincompatiblecc while
autoconf does, but at least BitlBee's configure script still runs in <1s.
