RFA: i386/nbsd.mt, i386nbsd-nat.c
- To: gdb-patches at sourceware dot cygnus dot com
- Subject: RFA: i386/nbsd.mt, i386nbsd-nat.c
- From: jtc at redback dot com (J.T. Conklin)

I submit the enclosed patch for approval. This change splits out
NetBSD native support from the FreeBSD, BSDI, and 386BSD support. The
changes I submitted earlier today convert the NetBSD target to use the
generic floating point register support, which conflicts with i386b-nat.c
