bjam keeps recompiling my libraries

Hi there,

I have a really odd problem on AIX with the latest bjam from the cvs. It 
keeps recompiling my libraries!

The following shows the Jamfile I used:

subproject test/boost/bjam ;
lib foo : foo.cpp ;

Attached is the output of bjam -d+3 when the library is up to date. If I 
understand this output correctly it decides that foo.cpp is newer than 
libfoo.a but the modification times are the other way round.

This is quite strage...
