+ Since the IRIX 4 configuration was forcing K&R mode it hasn't been
+ buildable since GDB 5.0.
+ * NEWS: Mention that IRIX 3 and IRIX 4 support were removed.
+ * configure.host: Delete "mips-sgi-irix3*" and "mips-sgi-irix4*".
+ * configure.tgt: Delete "mips*-sgi-*" a.k.a. irix3.
+ * irix4-nat.c: Delete file.
+ * config/mips/irix4.mh: Delete file.
+ * config/mips/irix3.mh: Delete file.
+ * config/mips/irix3.mt: Delete file.

2003-09-10 J. Brobecker <brobecker@gnat.com>
* hppa-tdep.c: Include "dis-asm.h". Fixes a build failure.
and its very obscure effet on GDB's prompt, was never documented,
tested, nor mentioned in the NEWS file.
+* REMOVED configurations and files

+SGI Irix-4.x mips-sgi-irix4 or iris4
+SGI Iris (MIPS) running Irix V3: mips-sgi-irix or iris

*** Changes in GDB 6.0:
* GNU/Linux support for fork, vfork, and exec.
