Thanks. Removing sfio from configure.in and reconfiguring/making did the job.
I didn't try it before because I figured Postgresql may have actually been using
sfio for something.

sfio is AT&T's replacement for stdio. It is available at
http://www.research.att.com/sw/tools/sfio/

The reason for using it on Solaris is because Solaris can't fopen file
descriptors above 255. So if you have a process that has more than 255 open
files in a process any further fopens will fail mysteriously (I have forgotten
what the error message is, but it is something like EPERM or something stupid
like that).

Here is a link to the Solaris FAQ that describes this:
