Hi Ken,

that's more or less what Karl originally had.  But at that time the cygwin
binary was named biber (and later renamed biber.exe).  Thus I'd prefer a
solution that works for both names. According to my tests "test -r foo"
detects foo.exe but not vice versa.  Thus testing first with and then
without .exe should do it, e.g.:

   biber_bin="bin/$TL_PLATFORM/biber"
   if test -n "$ac_exeext" && test -r "$srcdir/$biber_bin.exe"; then
     BIBER_BINARY="$biber_bin.exe"
   elif test -r "$srcdir/$biber_bin"; then
     BIBER_BINARY="$biber_bin"
   else
     BIBER_BINARY=
   fi

Could you please test this (with the binary named biber or biber.exe)

Regards
Peter
