[Lazarus] rewriting of LConvEncoding

[merlin352 at globe.lu]

Hi,

currently under Windows XP, Lazarus 0.9.28.2 r22279 FPC 2.2.4 i386-win32-win32/win64

i get a lot of 'No variable 'x' in current context' hints when I stop (set breakpoint
and step into/over a line) and hover a mouse over the variable.

I found 
http://www.mail-archive.com/lazarus@lists.lazarus.freepascal.org/msg07399.html
and
http://www.mail-archive.com/lazarus@lists.lazarus.freepascal.org/msg07401.html

- the latter suggests to rebuild RTL and LCL with dwarf debug info and "-Xg" for
application -

Having -g, -gl, and -gw, and also -Xg options checked in Compiler options, renders
breakpoints unusable (they go to invalid state upon hitting F9).

Hints ?
