One more time, with Changelogs. This fixes my broken headers, plus a lot of other source files which brokenly assumed that converter.h would include LStrings.h and/or support/lstrings.h for them (and I've removed it from there). It also adds #include <config.h> to LoaderQueue.C and forkedcallqueue.C.
There are still some remaining files which do not include <config.h>. Are they exceptions to the general rule? grep -L -r '<config.h>' `find . -name \*.C` ./frontends/controllers/ControlTabular.C ./frontends/controllers/Kernel.C ./frontends/qt2/bulletstrings.C ./frontends/qt2/qcoloritem.C ./frontends/qt2/qfontexample.C ./frontends/qt2/qgridview.C ./frontends/qt2/qsetborder.C ./insets/insetbase.C ./mathed/command_inset.C ./mathed/math_diffinset.C ./mathed/math_diminset.C ./mathed/math_fracbase.C ./mathed/math_fracinset.C ./mathed/math_gridinset.C ./mathed/math_inferinset.C ./mathed/math_lefteqninset.C ./mathed/math_liminset.C ./mathed/math_macro.C ./mathed/math_macroarg.C ./mathed/math_macrotemplate.C ./mathed/math_matrixinset.C ./mathed/math_nestinset.C ./mathed/math_parboxinset.C ./mathed/math_pos.C ./mathed/math_rootinset.C ./mathed/math_scriptinset.C ./mathed/math_spaceinset.C ./mathed/math_splitinset.C ./mathed/math_sqrtinset.C ./mathed/math_stackrelinset.C ./mathed/math_textinset.C ./mathed/math_undersetinset.C ./mathed/textpainter.C ./tex2lyx/texparser.C
