--enable-pch option is broken?

Hi,

on 2013-03-02 06:59:39 that commit
d221ae0092568e096f3850344a59ec27b4ea8efa
moved "svtools/fltcall.hxx" from svtools to
vcl/inc/vcl/fltcall.hxx

on 2013-03-07 this gerrit change was (twice) failing to build on Windows 
only
https://gerrit.libreoffice.org/#/c/2578/u
with the error:

c:\lo\gerrit_core\svx\inc\pch\precompiled_svxcore.hxx(510) : fatal error 
C1083: Cannot open include file: 'svtools/fltcall.hxx': No such file or 
directory
make[1]: *** [C:/lo/gerrit_core/workdir/wntmsci13 
<https://issues.apache.org/ooo/show_bug.cgi?id=13>.pro/PrecompiledHeader/nodebug/precompiled_svxcore.hxx.pch] 
Error 2

Looking for that moved svtools/fltcall.hxx in the old location.

If cou check the corresponding log you can see, that '--enable-pch' 
option is enabled on that TB:
https://ci.libreoffice.org/job/buildbot/339/?

Can we please somehow fix that or remove that option from tinderbox?
In the end nothing is more annoying then a broken tool chain.

Thanks
David
