No, it's a typedef in <sys/types.h>, which clashes with the libgfortran.h
definition:

typedef longlong_t      offset_t;

vs.

typedef off_t offset_t;

Certainly: off_t is in POSIX.1, and I currently see no reason to invent
anything g95 specific.  If there is, the type should be called gfc_offset_t
or something like this to avoid the clashes.

Depends on what is desired here.
