Hi,

I came across what seemed to be a bug in the garbage collector in
5.0.2. In the printing sample "virtual" functions are set for the
wxLuaPrintout which get called instead of the c++ functions. However
in the print preview if you changed the size of the preview a few
times the functions you set (even if global, not local) would get
garbage collected.
weird...
Anyway, this prompted to me try 5.1 and so far the results are very
good, this bug was fixed and it's MUCH FASTER! (yes using capitals is
appropriate, it's pretty impressive)
very good news !
It compiles and runs using the "Makefiles" in the src dir of the
apps/XXX dirs. All the samples have been updated, but not thoroughly
tested.
I've updated bakefiles but now, when I try to run wxluaedit I get a
segmentation fault... (this with wx2.6.3 and with an up2date
wxStedit...); other apps and samples I've tried work fine.
-------------------------
Some notes on the changes for 5.1 that I've come across, there's more...
1) lua 5.1 does not have an "include" dir so I faked it by copying the
pertinent headers that we use into it.
if you want to keep the header files in lua/src/ folder it's fine for me
as it's not a problem for bakefiles ;)
2) All the sources are in lua/src, even the lua and luac programs.
Please see modules/luaINSTALL for the list of files for each.
(Francesco, could you update the bakefiles? I don't think your *.c
trick will work anymore)
I've updated the bakefiles using the list of source files provided in
lua/INSTALL...

3) DO NOT CALL luaopen_XXX (eg luaopen_io for the io.XXX table). IT
WILL CRASH after some invalid reads. You have to open the libs a
little differently, I'm just using the function "luaL_openlibs" in
lua/src/linit.c which loads them all, but shows you how to do it
individually.
4) "for k, v in sometable do" is now "for k, v in pairs(sometable) do"
5) table.getn and table.setn are gone, use the #sometable to get the
count of the consecutive integer indexes in a table.
6) math.mod -> math.fmod and string.gfind -> string.gmatch
etc, see bottom of
