This morning's FreeBSD-32 trunk regression finished suspiciously quickly, though it appeared at first glance to have run normally. (I.e., didn't bomb immediately like when bjam can't find a file.)

Sure enough: there's a big gap in matrix, as though a bunch of tests were skipped.

If anyone has a burning desire to troubleshoot, it, I threw bjam.log up on dropbox. I poked around it a little but nothing jumped out at me. (I didn't scour the entire 21MB.)

This looks like my error.
unknown pid -1 with errno = 10
I want to disable use of vfork() on your system (and make a change to print more information if an error is detected). Is there a macro that is unique to the FreeBSD OS that I could use to identify your system?

I use #if defined(__FreeBSD__), but here's the full dump (from gcc -dM -E - <<<'')
