As far as I can tell, the really really important one is this:
dest_names_size=300000

The reason I say it is important is that I got a little more slap-happy in
adjusting the memory limits in that file.  I changed all  kinds of things and
still ran out of "destinations."  As far as I can tell, the dest_names_size
starts of at 20000, and it has an impact on how many hyperlinks you can have in
a file.  As you know, doxygen generates an amazing amount of hyperlinks.  It
doesn't have a default value in that file, so it's kind of a stealth option.  It
doesn't appear on many searchable web pages, either, so finding it via google
was quite difficult.  Here are all the other values I changed from the defaults.

main_memory.context = 4000000
main_memory = 2000000 
extra_mem_top = 21000    
extra_mem_bot = 21000    
obj_tab_size = 256000
hash_extra.context = 45000
hash_extra = 40000
pool_size.context = 7500000
pool_size = 2250000             
string_vacancies.context = 65000
string_vacancies = 65000
max_strings.context = 85000
max_strings = 85000
pool_free.context = 100000
pool_free = 21000
dest_names_size=300000 
trie_size = 30000
save_size.context = 10000
save_size = 20000       
stack_size.context = 3000
stack_size = 3000       
ocp_buf_size = 40000    
ocp_stack_size = 40000

I'm building under Win98 (ugh).  I have cygwin 1.3.13-2 (according to 'cygcheck
-s').

No.  I did:
./configure --english-only --prefix /usr/local -platform win32-g++

And it built out of the box and ran just fine the first time.
