Short version:
The "expr: Paren problem" comes from having /usr/ucb/bin ahead of
/usr/bin in one's $PATH.
So, I needed to fix my $PATH.
Long version:
This error is coming from configure's own argument parsing logic when
the ROMIO sub-configure is invoked.
The issue appears to be that the expr implementation of parens (for
match capture), doesn't like the length of the match.
This works:
$ expr 'XCPPFLAGS=-D_REENTRANT -I/foo/bar' : '[^=]*=\(.*\)'
-D_REENTRANT -I/foo/bar
This (from config.log) does not:
$ expr 'XCPPFLAGS= -D_REENTRANT
-I/export/home/phargrov/OMPI/openmpi-trunk-solaris10-x86-ss12u3/openmpi-1.7a1r25959/opal/mca/hwloc/hwloc132/hwloc/include

expr: Paren problem
This one works:
expr 'XCPPFLAGS=-D_REENTRANT
-I/foo/bar/baz/1234567890/acdefghijklmnopqrstuvwxyz/this-is-getting-too-long-for-solaris-expr-to-handle-correctly/'
: '[^=]*=\(.*\)'
-D_REENTRANT
-I/foo/bar/baz/1234567890/acdefghijklmnopqrstuvwxyz/this-is-getting-too-long-for-solaris-expr-to-handle-correctly/
While 1 more character breaks:
{phargrov@cloon BB}$ expr 'XCPPFLAGS=-D_REENTRANT
-I/foo/bar/baz/1234567890/acdefghijklmnopqrstuvwxyz/this-is-getting-too-long-for-solaris-expr-to-handle-correctly/1'
: '[^=]*=\(.*\)'
expr: Paren problem
The work-around appears to be to ensure /usr/bin is before /usr/ucb/bin
in PATH, since /usr/bin/expr doesn't display this problem.
I've fixed my own PATH accordingly for my future Solaris testing.
Even using /bin/sh, I saw no other "odd" behaviors with configure on
Solaris-10.

Argh!!
I am now trying to track down "expr: Paren problem" on Solaris.
The dash shell on Linux doesn't reproduce this one, unfortunately.
