### [Fri Jan 17 18:06:18 JST 2014 : pho]
### The linker that comes with Darwin 9 & prior does not recognize the option
### "-no_compact_unwind" since compact unwind information is only
### introduced (and made default) as of Darwin 10. Note that this
### can't be worked around with transformation
### "rm:-Wl,-no_compact_unwind" because the linker option is baked
### into utils/config.ml and will later be used by the OCaml compiler
### itself.

### On NetBSD/i386, gcc optimisation, at least for version 4.4.1 (lang/gcc44),
### produces a binary which segfaults. The binary is used during part of the
### build process.
