I am porting grep 2.22 and the null-byte check fails.
This check creates a file called "in" with the content: 00 0D 0A
and a pattern file called "pat" with the content: 00 24 0D 0A
and then runs the command:
  LC_ALL=C
  grep -a -f pat in

As result I get the output:

null-byte: failed test: -a '\0$' does not match '\0'


Now the question arises if this is a DJGPP/DOS specific issue
or if this is a DOS/WINDOWS specific issue.  In other words,
has someone compiled or ported grep 2.22 with mingw and checked
if the testsuite passes.  I do not have mingw and would not like
to have to install it only to resolve this issue.

TIA,
Juan M. Guerrero
