After reading the FAQ and comparing with a direct build from upstream 
sources, I find the reason for that is that the FontDataBase file of the 
distributed package is, indeed, wrong.

Apparently the type1 font directory supplied by grace was replaced by a 
link to ghostscript's type1 font repository.  But the FontDataBase 
wasn't updated to match this change.  This mismatch causes xmgrace to 
baulk.  This change was made between revisions 5.1.24 and 5.1.25 of the 
cygwin package, which neatly explains why 5.1.24 works, but 5.1.25 does not.

This was most likely caused by the cygport file not doing the (rather 
unusual) 'make links' step of the original Makefiles, but rather doing 
their own tweaking.  The 'grace' link is only created by 'make links' 
--- there is no 'grace' created in ${GRACE_HOME}/bin.  I would consider 
that an upstream bug, albeit it a small one.
