Changing to std::abs works fine. I had to do the same in
src/mathed/math_xdata.C:214 (std::abs), src/mathed/math_charinset.C:52
(std::isalpha), src/mathed/math_cursor.C:1465,1549,1554 (std::isalpha),
src/mathed/math_mathmlstream.C:233 (std::strlen),
src/mathed/math_parser.C:781,897,903,909 (std::atoi).
Andre's suggestion ("using std::abs") works fine with cxx, too.
Going further:

IIRC Angus' suggestion was to move "typedef std::vector<InsetTable> InsetList;"
and "InsetList insetlist;" from private to public in src/paragraph.h.
If I do this, it compiles until:

IIRC Angus suggested "#include <ctime>" in src/insets/insetexternal.C
which unfortunately doesn't fix it. When I manually add
"-I$(top_srcdir)/src/cheaders" to CPPFLAGS in src/insets/Makefile
(configure decided to put "lyx_cv_cxx_cheaders=yes" in config.cache),
I get conflicts:

Well, with an ugly "#include <time.h>" it compiles.
Now I'm stuck at:

A cxx bug? (upgrade is not an option, this already is the latest version)
