Bug #9333: win32/Makefile.sub malconfiguration
https://bugs.ruby-lang.org/issues/9333

Author: arton (Akio Tajima)
Status: Open
Priority: Normal
Assignee: arton (Akio Tajima)
Category: platform/windows
Target version: current: 2.2.0
ruby -v: ruby 2.1.0p0 (2013-12-25 revision 44422) [i386-mswin32_100]
Backport: 1.9.3: UNKNOWN, 2.0.0: UNKNOWN, 2.1: UNKNOWN


win32/Makefile.sub defines HAVE_FSEEKO because win32/win32.c defined the function. 
However since r40661 the function was removed from win32/win32.c.
It must be removed from Makfile.sub too.
