Just a simple test I've done, though I don't know
what it means exactly:


[ptsekov AT nobel lib]$ ls -la

[ptsekov AT nobel lib]$ grep -n -e "/dev/null" *
Binary file libc.a matches
Binary file libm.a matches
Binary file libpthread.a matches

This are the same files that are listed in the 1.3.7-1 announcement:

- Create special versions of import library with only appropriate symbols
   for libpthread.a, libm.a, and libc.a. (Ralf Habacker, Christopher Faylor)


I dont know the details on how this special libs are build but from
what was posted on the list I know some kind of script is involved.
Maybe there is some error in the script or perhaps your usage of
-lpthread is not quite right and triggers the real problem. However
someone with more knowledge is needed to answer these questions :)
