Some core libraries use off_t or struct stat in public header files, so we
already have the ABI problem. Paul Eggert did some review and thinks that
64-bit-by-default fixes more things than it breaks:

In addition, <selinux/selinux.h> contains this gem:
extern int matchpathcon_filespec_add(ino_t ino, int specind, const char
*file);
Yeah, perhaps some packages do bogus and unsafe things. But by changing
_FILE_OFFSET_BITS, you change it silently for everything. C++ functions
using ino_t/off_t etc. will not link anymore, ...
You'd need to bump SONAME of all the affected shared libraries, etc.
IMNSHO you can do this kind of changes in a new port, but not afterwards.
