Hi All.
As part of testing gawk, Nelson Beebe builds it on a bunch of systems.
On MirBSD (which is some fringe BSD variant), the regx8bit test fails.
When gawk is run to bypass dfa, the test passes.
Grep 2.6.3 does not pass all its tests on that system. The ones that
fail are:
FAIL: test-mbrtowc3.sh
FAIL: test-mbsrtowcs3.sh
FAIL: test-wcrtomb.sh
The following is a good way to reproduce the failure with grep:
bash4.1$ echo -e 'a\xe5b' | grep $'\xe5'
This prints nothing on MirBSD and prints the line on Linux.
