Locale problems while building Pike

A Polish developer runs who ran "make" got this output:

Compiling tmodule.c
sed -e 's![^ -~]lib_prefix[^ -~]!/home/opera/instalki/pike-current/build/

make[2]: *** [master.pike] Error 1

With the following environment:

Ununtu sed 4.1.5 make 3.61 tcsh 6.14.00-7ubutu1

LANG=pl_PL.UTF-8 LC_MESSAGES=C

The following patch from Piotr Smyrak fixes it, but I'm unsure about the implications for legacy systems:
