Hi,
it's in there (I checked with dumpbin), but it won't come out. I am a bit
puzzled because
a) usually stuff like that should not happen,
b) aparently it only happens on Win,
c) I can't find a corresponding entry in the long list of MSVC compiler
bugs,
d) for some reason this does not happen to the root team building the
windows root binaries,
e) I have had root problems which often seem to be related to static
globals, too. Examples:
* static globals which were supposed to initialize the dictionary were not
called,
* trying to build root in Win2k myself does not work as the dictionary
doesn't add classes that were gSystem->LoadClass'ed (I'd guess it's a
problem with dlls and their statics),
* and now this guy.
I'm afraid that ignoring messages like

during the built of root takes its revenge here...
We can reproduce these problems on different computers and by different
people here at Fermilab, so it's hopefully not my stupidity or compiler
version.
Ideas? Maybe I should just deinstall Win and get Linux...
Cheers, Axel.
