- Building Emacs 21.1 and 21.2 on versions of Irix before 6.5.10,
- especially when Emacs is built with GCC, was reported to have subtle
- problems such as being unable to print to stdout under the -batch
- command-line option. Building with the native compiler or upgrading
- the OS to a newer version solves these problems. There's evidence
- that these problems are actually related to the runtime libraries
- (before IRIX 6.5.10, the IRIX runtimes were based on the MIPSpro 7.2
- compilers), so installing patches for the runtime from
- http://www.sgi.com/support/patch_intro.html could solve the problem
- even without upgrading the OS. The dump process is the crucial
- step that needs the upgraded runtime, so a workaround is to dump
- Emacs on a machine with a newer OS, then copy the binary to the
- older OS.
