is because the DJGPP `ln' emulates soft links for executables by
generating a stub that in turn calls the real program. This
feature also works with nonexistent files like in the Unix
spec. So `ln -s X conftestdata' will generate `conftestdata.exe'
which will attempt to call 'X.exe'. But this feature only works
for executables. Fix it.
* acspecific.m4 (AC_PROG_LN_S): Create a sample file and use it to
