So I downloaded and extracted the source for 1.1.27 into ~/wine, saved what you posted as ~/wine/tapi32.diff and ran "patch -p1 < tapi32.diff" and was given the following output: Code: patching file dlls/tapi32/phone.c Hunk #1 FAILED at 205. 1 out of 1 hunk FAILED -- saving rejects to file dlls/tapi32/phone.c.rej patching file dlls/tapi32/tapi32.spec Hunk #1 FAILED at 144. 1 out of 1 hunk FAILED -- saving rejects to file dlls/tapi32/tapi32.spec.rej patching file include/tapi.h Hunk #1 succeeded at 846 with fuzz 1. Did I miss a step somewhere?
