[linuxdc-dev] gcc, libstdc++, and ".hidden" patches

[Thomas <spi...@so...>]

hello all.  i was recently working on building a cross compiler toolchain to 
build opie ( http://opie.handhelds.org ) for the dreamcast.  i was following 
bill gatliff's instructions on linuxdevices.com relatively closely (had to 
change a couple of things because i need a dynamic linker), and was able to 
succesfully compile everything i needed.  however, when i was done, i could 
not run opie, getting anundefined reference to __udivsi3_i4 in libstdc++.  
after doing some searching on google, i found that this was due to the 
".hidden" patch. info:

(sorry for the long urls, but since geocrawler.com no longer exists, i have to 
use the google cache).

anyway, these all apply to the 3.0.1 version of gcc that i was using (and is 
mentioned in these emails), but later versions of gcc on m17n.org are for gcc 
3.0.4, so i was wondering if the patches for those versions still had this 
problem, or, if this is the wrong place to ask, where i could find out.  i 
really dont want to spend more time building another toolchain that wont work 
if i can avoid it : )

thanks for any help
