Hi,

when I try to use PCH on MICO project, I've got following error when compiling
orb/ssliop.cc file:

c++  -I../include -DFAST_PCH -Wall   -DPIC -fPIC  -c ssliop.cc -o ssliop.pic.o

The problem is that the problematics include files tries to include CORBA.h
which is precompiled to the CORBA.h.gch. When I remove CORBA.h.gch, compilation
continues well.

Analysis: there are a lot of files which include CORBA.h in orb directory and
which doesn't fail with this error. The difference between these files and
ssliop.cc is that non-problematic files includes CORBA.h file directly from cc
file (as the first include), while ssliop.cc includes only ssliop.h file which
then includes CORBA.h file (as the first include).

Cheers,

Karel
