Actually, via "confstr(_CS_PATH, buf, sizeof(buf))" one can find the path.
Nevertheless, calling "sh" assumes that one has a POSIX system; I am pretty
sure that it would fail on MinGW - even though, "system()" works there. Maybe,
one can use some configure check to know whether "sh" is available. However,
the check should be cross-compile friendly.
