About testsuite:
The last autoconf version which I was able to build for i586-pc-msdosdjgpp
was 2.61 if I remember correctly and then I had rather large number of
test failures. I have however run tests of autoconf-2.63 on x86_64-gnu-linux
both with patch applied and without them. No regressions found (no unexpected
failures in both runs).

I wanted to compare test results for mingw32, unfortunately building
autocond-2.63 for it does not work (at least not immediately immediately).
I suspect that the problems may be similar as with building latest
autoconf versions for DJGPP.

AWK version:
GNU Awk 3.16.

About thanks:
It's OK.
