Thanks, I adjusted ChangeLog, comment, and added the copyright year.
It would be kind, if somebody could apply this patch to glibc's
repository as I don't have commit access to it. I can do the applying
to gcc's tree, if patch is ok-ed.
ChangeLog glibc
2012-03-01 Kai Tietz <kti...@redhat.com>
* soft-fp/soft-fp.h (_FP_STRUCT_LAYOUT): New macro.
Adjusted copyright year.
* soft-fp/quad.h (_FP_UNION_Q): Mark bitfield-struct
part by _FP_STRUCT_LAYOUT.
Adjusted copyright year.
* soft-fp/extended.h: Likewise.
* soft-fp/single.h (_FP_UNION_S): Likewise.
* soft-fp/double.h (_FP_UNION_D): Likewise.
Thanks in advance,
Kai
