can't find libCrun.so.1 when compiling/linking

[Nevenka Bierny]

Hi, 
I'm trying to compile a C++ program on a Solaris sun4u / OS version 5.7 /
sparc-sun-solaris2.7. I'm using version 2.95 of g++. 
When I try to compile using the following: 
g++ -g -o Program Program.cpp -L. -lsocket -lnsl -lrt 
I get lots of undefind references.
The functions are located in libCrun.so.1. However, when I compile using 
g++ -g -o Program Program.cpp -L. -L/usr/lib -lCrun -lsocket -lnsl -lrt 
ld can't find libCrun. 
Any suggestions? Also, where can I find a listing of gcc releases / what
issues were addressed? 
Thanks,
