        An update of 27bugfixes.zip with this fix is available in:

        http://www.slcc.edu/fote/lynx/


        Did the 1997-03-26 change in the HTStream structure for
src/HTFWriter.c eliminate the segmentation faults when downloading
on linux.  If not, there must still be some memory management glitch
for linux which needs to be found in v2.7.
