Compile problems on Solaris 10

[Paul Goodman]

I am trying to compile the pam_radius-1.3.16 modules on a Solaris 10 system, but when I run make, I get the following error:

gcc -Wall -fPIC -c pam_radius_auth.c -o pam_radius_auth.o

The same is true when I use the Sun cc (Studio 11 compiler). I am using gcc 4.0.2 (the most recent version I could get to run on Solaris).
Output of uname -a is:

SunOS xxxx 5.10 Generic_118833-36 sun4u sparc SUNW,A70


Does anyone have a suggestion as to how to modify the header file to make it work or know where I can find pre-compiled modules for Solaris?
