link problems with precompiled headers and boost libs?

Hi,

I'm using the datetime library of boost 1_30_0 with VC7.1 with 
precompiled headers on. We're getting the following link 
warnings/errors:

om.lib(bg_extra.obj) : warning LNK4006: 
___@@_PchSym__at_00@UwvevolknvmgUtnkEPozhgUhlfixvUytPzwwOlyq@ already 
defined in om.lib(bg_init.obj); second definition ignored

om.lib(bg_extra.obj) : error LNK2005: 
___@@_PchSym__at_00@UwvevolknvmgUtnkEPozhgUhlfixvUytPzwwOlyq@ already 
defined in om.lib(bg_init.obj)

We include boost headers in our own header files. Our own headerfiles 
are then used to create a precompiled header. It seems that all 
object files that use the precompiled header get these link errors...

Does anyone know the reason/ a solution for this error?

Thanks a lot!
