If you can't get a safe library, you can do the following:
Extract from any library you want the modules you need using "ar"
(man 1 ar). You can then link them one-by-one to your object modules or you
can use "ar" to create your own library.
I have done this several times to get the long-long division function from
libgcc and it works perfectly. I have done this (in just one project) with
other libgcc library modules too.
Of course you'll have to extract from the library (or libraries) any
modules containing other functions that the modules you first extract
require. Use "objdump" (man 1 objdump) to determine what other -- if any --
functions/modules are required (and by extension, determine what might not
be safe).
