It would be nice if it was possible to put the precompiled header in a
subdirectory.
For example, here is what I tried to do (my sources are in GFL/):

# Pre-compiled header
cpp-pch PreCompile
    : GFL/PreCompile.h
    : <toolset>msvc:<source>GFL/PreCompile.cpp
    ;

lib GFL-1_0
    : PreCompile                               # Pre-compiled header
      ...
    ;

This works with gcc toolset, but not msvc. The problem is that I include
"GFL/PreCompile.h"
in all cpp-files but the compiler switch is -Yu"PreCompile.h". It has to be
-Yu"GFL/PreCompile.h".
Otherwise the compiler complains:

compile-c-c++ bin\msvc-7.1\debug\threading-multi\Alignment.obj
Alignment.cpp
C:\projects\trunk\GFL\GFL\LandXML\Alignment.cpp(139) : fatal error C1010:
unexpected end of file while looking for precompiled header directive
