That's not a problem, unless:
FILE*f;
int result;
int ch;
f = popen("xcopy non_existing_file", "r");
while ((ch = getc(f)) != EOF);
result = pclose(f);
returns 256, and if WEXITSTATUS is defined as (status>>8)&0xff. Can
someone with mingw access confirm if this system() bug is widespread?
I've already checked that cygwin is not affected.

If they do, then I will try to write a module that does an AC_RUN_IFELSE
using something similar to the above; compare the results of popen and
system on the same command known to fail without producing output, and see
if the return values are the same.
