Compile problems under Solaris 9

Tried with both GCC 2.95.3 & 3.2.1, I get the following error:

authclnt.C: In function `bool validshell(const char *)':
authclnt.C:102: implicit declaration of function `int setusershell(...)'
authclnt.C:103: implicit declaration of function `int getusershell(...)'
authclnt.C:103: assignment to `const char *' from `int' lacks a cast
authclnt.C:105: implicit declaration of function `int endusershell(...)'

Way over my head as to why this is happening.

Any hints?

Thanks,

A.
