Why so?  A target is supported when it gets mentioned in
release-notes.   The gcc 4.8.x doesn't support that target.  There is
the 4.8.x version cygwin uses for building cygwin 64-bit.  The used
gcc version is locally patched.  You can get those patches (actual
back-merge of changes already applied to trunk plus some additions
AFAIK) by the cygwin-folk directly.
