APIENTRY is unconditionally defined through windows.h while it already has
been defined previously in oglpfuncs.h, resulting in a macro redefinition
warning. In this case fix the warning by undefining the macro prior to
including windows.h.
Update misc/scripts/inc_release script: remove non-existent any more files and
update the version in the MSVS 200x project files not generated by bakefile
any more and MSVS 201x project files which were not previously taken into
account.
Run it and rebake.
