The package that hosts the instance of gnulib on which the failure was
observed is GnuTLS-3.1.5. I'm not sure whether it replaces fseek or
not, i don't see anything like that in its configure.ac, and there is
no special configure for its gl subdirectory. However, that
subdirectory does have fseek.c and fseeko.c, and m4 subsubdirectory
has fseek.m4. But fseeko.o or fseek.o are not produced when the
packages is compiled.

Apparently, the MSVCRT implementation  of fseek() is used.

I'm unsure of how they work.
