-nostdlib option!

[Manuel Coutinho]

Hi

Other mechanism: supply your own memset, memcpy, etc.
If you do this, the linker will know which memset, memcpy, etc to use and
will not complaint about not using libc.

I have copied part of gcc manual:
------------------------------------
Do not use the standard system startup files or libraries when
linking.  No startup files and only the libraries you specify will be
passed to the linker.  The compiler may generate calls to "memcmp",
"memset", "memcpy" and "memmove".  These entries are usually resolved
by entries in libc.  These entry points should be supplied through
some other mechanism when this option is specified.
------------------------------------
What is some other mechanism? How can i use -nostdlib?
