hi folks.
a very long time ago in netbsd years tls@ patched GCC to use /tmp over /var/tmp, for the compiler temporaries. i tried to keep these patches, but they got lost at some point and when i recently wanted to deal with it (i had one machine with some several hundred /var/tmp/cc*.o files that were mostly over a year old), i discovered it's not nearly as simple as a quick patch. most of the toolchain consumers that create temp files don't use $TMPDIR from the env but use stdio.h's P_tmpdir defintion which we have set to "/var/tmp". i pondered how to patch the toolchain to deal with this sanely on netbsd, but it would require a fairly non trivial patch to the relavant libiberty files (and then some more) and only be for netbsd. so, i decided i'd try running with stdio.h patch instead and it works fine (of course.) i didn't see much software around that uses P_tmpdir, so i think it's probably safe and fine to change to /tmp. any objections? thanks. .mrg.
