[En-Nut-Discussion] SVN compilation fix: fs/fat.c

[Uwe Bonnes]

Hello,

with (avr-)gcc version 4.4.1 [gcc-4_4-branch revision 150839] (SUSE Linux)
recent Sourceforge SVN doesn't compile nut/fs/fat.c:
cc1: warnings being treated as errors
../.././/fs/fat.c: In function 'MountATAPI':
../.././/fs/fat.c:934: error: dereferencing type-punned pointer will break strict-aliasing rules
../.././/fs/fat.c:935: error: dereferencing type-punned pointer will break strict-aliasing rules

Appended patch defines the structure with the types later used.

Bye
