QDir::mkpath() fails when creating paths that start '/cygdrive/'. This
problem is only shown with Qt5 (not Qt4), and only with paths that start
'/cygdrive/' (so running from my home directory '~' is fine). This is
not a permissions problem, as it works fine with Qt4.
Sample programme is below. Compile for Qt5 as per the comments. 'cd
/cygdrive/X' where X is a local drive where you have permissions to
create a directory. Run './create_directory new_dir' and it fails to
create the directory. Programme works fine when compiled with Qt4.
I am using libQt5Core5-5.4.1-4 and libQt4-4.8.7-1 under cygwin-2.0.4-1.
I haven't had chance to try with Qt 5.4.2 (announced yesterday), so
apologies in advance if this is fixed already.
