Candidate for most silly question, but here it goes:

Hi!

#> file /usr/lib/libc.so
/usr/lib/libc.so: ASCII text


#> cat /usr/lib/libc.so
/* $FreeBSD$ */
GROUP ( /lib/libc.so.7 /usr/lib/libc_nonshared.a )


Does this make sense in any way?

Accidentally stumbled across while trying out thunderbird, which claims:
JavaScript error: resource:///modules/CLib.jsm, line 46: Error: couldn't 
open library libc.so: /usr/lib/libc.so: invalid file format


Thanks for hints (I have some brief knwoledge about dynamically linked 
binaries, but I'm not aware of linker hints - which is what I see to my 
understanding).
