Work around to use longer paths(more than 80 characters) in command AC_QUOTE.

* create a batch file (e.g. abc.bat) and in the batch the AC_QUOTE command as follows:
AC_QUOTE CHMOD 664 /very/long/...../path/&(file_name)

or

make a "link" to path /very/long/....../path/ and use the command as follows:
AC_QUOTE CHMOD 664 /link/&(file_name)
