Dave,

thx. for the clarification about the apostrophes!

As to -fno-leading-underscore: I had this in my cygwin gcc3.* makefiles 
now for a couple of years (dunno where it originated).

Compiles & links fine without! It's gone down the crapper for good...
Now I'm one happy gcc4/gfortran guy!

Thanks again for your knowlegdable help!

H.
