strange luaL_loadfile behaviour

[Enrico Tassi <gareuselesinge@...>]

I call (lua 5.0.2)

rc = luaL_loadfile(l,FILE_PATH)

and the rc returned is != 0, so I read the top of the stack and I
find...

"cannot read lua/freepops.lua: No error"

the file exists and it sometimes works...
The problem happens under windows...

today I'm a bit lazy and I've not looked inside lua sources... but ...
what error message is this one?

now I'm really tyred and I'm gong to bed... maybe tomorrow I'll
investigate more... but, before loosing time: anybody received 
this odd error message?

thanks
