There is no SUBREG_BYTE patch which would apply to 2.95.x. Plus this patch
touches almost all files in gcc, so backporting would not be easy.
As stated, it was not part of any compiler released by FSF.
The tested configurations are gcc-2.96-RH, there is a patch floating around
for 3.0 and finally it was commited into trunk after 3.0 was branched off.
