Thanks to everyone who offered a suggestion -- I don't
have crm114 building yet, but I at least feel like I
am BEGINNING to understand the link (not well enough
however.)

Will do.  (If I can figure out where.)

There is a /bin/cygintl.dll, and in /lib there are:

	libintl.a libintl.dll.a libintl.la

If I change -L/usr/local/lib to -L/usr/local/lib:/lib
the problem moves to "-ltre"; if I leave out the :/lib
or try to use a separate -L/lib then the errors messages
references libintl again.  (Obviously, I am just flailing,
trying each combination.)

TRE makes and tests just fine.  Do you think that TRE
is (the cause of) the linking problem or just the target?

crm114 doesn't use configure.  Did you intend this 
for TRE (which doesn't seem [to me] to be the cause 
of the problem.)

And since the TRE is set to static (by configure instruction
when TRE is made), TRE shouldn't be the problem. ???

So, as I understand it, the TRE libs in /usr/local/lib
make sense, correct?
