I still hate those machine-dependent defaults, though: if you have old mips3-only machines around, you have to be careful when building on a mips4-machine ;-(. I really think the default should be last-common-denominator (i.e. n32/mips3). > Yes, the /etc/compiler.defaulst specifies both ABI and ISA.

Exactly: only SGI makes such a mess out of this situation. Other companies default to (say) SPARC V7 or Alpha EV4, with options to allow for code optimized for the compilation machine. Rainer
