BCB++ 1.0 does not rebuild component library

Hi,

from one to the other day the linker fails with an error message like
"assertion failed" whenever I try to install a new component in C++
builder 1.0.

My programs, however, can be compiled und linked without any problems.

Borland's FAQ2027C.txt says "you _must_ exclude any headers which have
typedefed instantiations from the precompiles headers."  and suggests
to use the "-He-" option.
The latter does however not solve my problem. What else can I do?
Plz post answers.

Thanx in advance
