Subject:	Re: gdb 7.8 consistently fails to run executable - error is
MIME-Version:	1.0

Hi Dominik,

In my case, it was not down to the string size being too small. I seemed to
suffer exactly the same problem.

You get the same error if Windows can't access the dll. This seems to happen
for some "special" dlls.

The size of any PATH variable won't matter - the path it refers to here is
the "realpath" conversion of the dll filename.

The simple patch applied makes gdb work for me on Windows 7.
