Personally see no problem. The quote above has specifically to do with how to write a logical 16-bit timer/counter value into a pair of otherwise distinct 8-bit registers, which controls a specific peripheral function which presumes a specific write sequence to maintain the logical integrety of that specific timer/counter value; it has nothing to with 16-bit pointers, the sequencing of multi-byte logical data type transactions, or the compiler in general. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=20288
