## gcc version 4.4.0 20090506 (Red Hat 4.4.0-4) (GCC) is a PITA:
|

## const char *ptr; ... off_t v = *(off_t*)ptr; -> BOOM
|
||||
## and no easy way to convince it to shut the hell up.
|
||||
## We have a lot of such things all over the place.
|
||||
## Classic *(off_t*)(void*)ptr does not work,
|
||||
## and I am unwilling to do crazy gcc specific ({ void *ppp = ...; })
|
||||
## stuff in macros. This would obfuscate the code too much.
