patch-ad:
src/tools/qglobal.h mentionss about Q_NO_PACKED_REFERENCE:
---
/* ARM gcc pads structs to 32 bits, even when they contain a single
char, or short. We tell gcc to pack QChars to 16 bits, to avoid
QString bloat. However, gcc 3.4 doesn't allow us to create references to
members of a packed struct. (Pointers are OK, because then you
supposedly know what you are doing.) */
# if (defined(__arm__) || defined(__ARMEL__)) && !defined(QT_MOC_CPP)
# define Q_PACKED __attribute__ ((packed))
# if __GNUC__ == 3 && __GNUC_MINOR__ >= 4
# define Q_NO_PACKED_REFERENCE
---
but it seems we also have to define it on gcc4.
patch-ch:
Furthermore, it looks gcc4 also rejects implicit pointer casts, so
add an explicit cast where the above Q_NO_PACKED_REFERENCE is referred.
