[svn-r8252] Purpose:
bug fix new test Description: the fletcher filter used a temporary 2 byte word buffer to compute the checksum. this is non portable between big-endian/little endian. added a test that reads 2 pre-saved files (one LE, other BE) with that filter enabled Solution: replaced with a buffer of 1 byte type Platforms tested: linux solaris solaris 64 bit AIX windows Misc. update:
