gdb 7.8 consistently fails to run executable - error is
Mon Sep 29 14:18:00 GMT 2014
I've dug into the gdb sources.
The problem is in the cygwin-only part and is not about the PATH
variable but about one single DLL file name.
This path length is *fixed* to 512 characters (SO_NAME_MAX_PATH_SIZE)
for the *realpath* of the DLL.
So there's no way for the user to work around this apart from shortening
the directory or file names.
