[PD-dev] open_via_path() weirdness

[IOhannes m zmoelnig]

hi all,

in the course of trying to find the filehandle-leak bug in Gem i found a 
weird problem with open_via_path().

can anybody find anything wrong with the attached code?
if not, try the attached patch as well.

everything works fine on linux, but on w32 i cannot close the 
file-handle anymore (i get an errno of EBADF, which means that fd isn't 
a valid open file descriptor).
which in turn results in a filehandle leak.

i notice that hardly anyone (esp. Pd itself) uses open_via_path().
is there a reason for that? is it buggy? (couldn't find anything wrong 
though)

i use it quite a lot, e.g. in [msgfile]; i guess nobody ever tried to 
open > 1000 files with msgfile on w32, so the error never appeared...
