This is larger then needed mainly because I wanted to make the macro
HPUXDYNAMIC$ more descriptive as HPUX10DYNAMIC. Let me know if that's
too much, and I'll take that piece out.
The other thing was to split the hpux cases from solaris to initialize
DL_EXT there. I expect it should be alright to remove Hcurses from the
solaris list, but I have no such access to verify that.
