Details:

Starting an application by entering the name of the symbolic link on the
command line does not work anymore. Applications started in that way will fail
with an error saying that they cannot find their main nib file. Starting the
application with openapp or by entering the full path of the main executable
file still works.

The problem can be observed on every platform where NSBundle's
GSPrivateExecutablePath returns a relative path when the application was
started without entering the full path of the application's main executable,
which seems to be every platform out there except Linux, and was introduced in
r32109 when NSString -stringByStandardizingPath stopped resolving symbolic
links. For instance, the path of an application's main bundle does not resolve
to the application directory but to the tools directory containing the
symbolic link instead.

Simply changing all calls to -stringByStandardizingPath into
-stringByResolvingSymbolicLinksInPath does not work either, apparently because
the latter method converts all relative paths into absolute paths by
prepending the current directory. (BTW, this behavior seems to be incompatible
with OS X as well; I tried that for a few simple cases including [@"."
stringByResolvingSymbolicLinksInPath] and [@".."
stringByResolvingSymbolicLinksInPath] and OS X doesn't seem to convert
relative paths into absolute paths.)
