Gnat 3.09 Linux errors

[stumpem@email.uah.edu (Michael A. Stumpe)]

Hello,

  I have just installed package gnat-3.09-i486-linux-elf-bin.tar.gz (Gnat
3.09) for use with a Computer Science class.  I am using GCC version
2.7.2.1, and I am getting the follow errors ...

...
[mast@ccrhsa033 cs424]$ gnatmake totem_pole.adb
gcc -c totem_pole.adb
gnatbind -x totem_pole.ali
gnatlink totem_pole.ali
/usr/lib/libpthreads.so.1: the `gets' function is dangerous and should not
be used.
/usr/lib/libpthreads.so.1: undefined reference to `__libc_rewinddir'

/usr/lib/libpthreads.so.1: undefined reference to `__libc_telldir'
/usr/lib/libpthreads.so.1: undefined reference to `___masksig_restore'
gnatmake: *** link failed.
...

Does anyone know what this is?  Does the rest of the output have to do
with the 'gets' function being 'dangerous'?  That libpthreads library *is*
the one that came with the gnat package, I have checked.  I can't see how
this would be a problem with GCC, since it compiles fine, but messes up
at the point of Gnat linking.


				Thanks to all,
