I did a hexdump of my most recent Linux lib (libc.so.5.3.12) and found
that a grep like:
grep "The Linux C library" libc.so.5.3.12
yields:
,/@(#) The Linux C library 5.3.12Uknown uid_t size and sign
Unfortunately, when I tried this neat thing on various other libc versions
I have littering around, the response wasn't reliable, so I'm sorry, I
haven't any reliable way to tell this. I know some folks who know Linux
fairly well; I'll ask and see what kind of response I get. I'll look for
something that would not need the linux toolset to accomplish.
