I would just apply the patch with the usual patch command, Strawberry supplies it:

VinsWorldcom@C:\Users\VinsWorldcom> which -a patch
C:\usr\bin\patch.BAT
C:\Strawberry\c\bin\patch.EXE
C:\usr\bin\git\usr\bin\patch.EXE
[download]

It's usually something like:

patch -p1 < Object-Import-1-004-RT106769.patch
[download]

... but I usually reference this.
