* Makefile.in (clean-platform): add new target.
It cleans `win32` directory.
* common.mk (clean): add a dependency for `win32` directory.
* common.mk (distclean): ditto.
* common.mk (distclean-platform): add new target.
It cleans `win32` directory.
* common.mk ($(PLATFORM_D)): add new target to make `win32` directory.
* common.mk (win32/win32.$(OBJEXT)): move win32.o into `win32`
directory.
* common.mk (win32/file.$(OBJEXT)): add new target for win32/file.c.
* configure.in: move win32.o into `win32` directory and add
win32/file.o to MISSING.
* file.c (file_load_ok, rb_file_load_ok): replace static
file_load_ok() with public rb_file_load_ok().
It's to link Windows implementation in win32/file.c.
* file.c (rb_find_file_ext_safe): ditto.
* file.c (rb_find_file_safe): ditto.
* win32/file.c (rb_file_load_ok): new file. Add Windows specific
optimized implementation of rb_file_load_ok(). We created a
separated file to avoid too many #ifdef macro which is unreadable.
* win32/Makefile.sub (PLATFORM_DIR): add a variable for `win32`
directory.
* win32/Makefile.sub (MISSING): move win32.obj into `win32`
directory and add win32/file.obj to MISSING.
* win32/Makefile.sub (MAKEDIRS): replace MINIRUBY with BASERUBY.
It's because miniruby doesn't exist when making `win32` directory.
* win32/Makefile.sub (clean-platform): add new target to clean `win32`
directory.
* win32/Makefile.sub ({$(srcdir)}.c{}.obj): make it not match
win32/file.c to build properly.
* win32/Makefile.sub (win32/win32.$(OBJEXT)): move win32.obj into
`win32` directory.
Patch created with Luis Lavena.
