It will take time for me to look in grep, because I'd need to build my
own binary from sources.

For Gawk, the configure-time test is not going to solve the problem on
Windows because the Windows port of Gawk does not use the configure
script, it is built using a separately maintained Makefile.  So for
Gawk, I can simply put the replacement wctob on a Windows-specific
file (which exists anyway, for other functions that need wrappers or
replacements).

Thanks.
