Doubt about __register_frame_info and __deregister_frame_info.

[Koundinya K <knk at dde dot dk>]

Hi all,
   If you have followed my earlier mail regarding g++ and .gnu.linkonce
sections which I am trying to enable for my mips-sysv4.2 based platform,
I am having the problem undefined references to the symbols
__register_frame_info and __deregister_frame_info in stage1/gencheck and
other gen* friends. :) while bootstrapping.

I read quite a lot about these on the past mailing list archives, where
this has been a topic of discussion. 

Apparently as I understand since on linux these functions are present in
the 'C' library, the references to these have been made weak in the
crtbegin.o and crtend.o

(Linux Users please pardon me if I am wrong. Please Bear with my
ignorance). 

For Non linux based systems, should the references for these symbols be
still weak in crtbegin.o and crtend.o ?.

Could someone throw some light on this and clear my doubts ?

Thanks
