Bug 1108 - IOUtil.getTempDir(..): Difficulties to determine executable access permission on Windows via BATCH file execution

Try using explicit call to Windows 'cmd.exe' w/ referencing the BATCH file location,
via
  'Runtime.getRuntime().exec(new String[] { "cmd", "/c", "a.bat" } );'

While the bug itself could not be reproduced here,
I could test on Windows 7 (64bit and 32bit), as well as an WindowsXP 32bit
that no regression occured.
GlueGen JavaEmitter: Use proper class access modifiers for emitted classes incl. ProcAddressTable

Emitted Java classes as well as optional ProcAddressTable shall
use unique generated access modifiers covering all MethodAccess cases.
