Hi,
 The problem is due to the fact that GCC 2.95 has changed it's 
inline assembly support. Thus older programs which compiled well 
using 2.81 give errors in 2.95 (invalid asm etc).

So my quick fix was to download  GCC 2.81 (gcc281b.zip) install it 
and use it to compile libamp and get the LIBAMP.A file and the 
examples. 

And then (since I use gcc2.95 like you) I reinstalled  GCC 2.95 and 
used it to compile my LIBAMP based program's linking with the 
LIBAMP.A file made by gcc2.81.

I hope this helps you as apart from rewriting the libamp files for 
GCC2.95 this was the only quick fix I could think of.

Bye!
Kalum
