Bernd's problem is that the line "ostr << ifs.rdbuf();" in lyx::sum takes ~260
seconds to read UserGuide.tex (he used gcc-2.95.3/libstdc++2.10-glibc2.2
with HAVE_SSTREAM defined). This seems like a libstdc++ bug.
However, on my machine (libstdc++2.9/gcc-2.91.66 with HAVE_SSTREAM undefined)
The line "ostr << ifs.rdbuf();" takes 0.17 seconds for UserGuide.tex, while
the old code (that used ostrstream) took 0.03.
So maybe we should use ostrstream again, until compilers get better.
