I just tried gcc and got:

#$ gcc -shared -soname libpsqlodbc.so.0 -Bsymbolic info.o bind.o
columninfo.o connection.o convert.o drvconn.o environ.o execute.o lobj.o
misc.o options.o pgtypes.o psqlodbc.o qresult.o results.o socket.o
parse.o statement.o gpps.o tuple.o tuplelist.o dlg_specific.o 
-L/usr/local/lib -L/usr/contrib/lib -lm -o libpsqlodbc.so.0.26
gcc: unrecognized option `-soname'
gcc: file path prefix `symbolic' never used
