compiling under solaris

[Frank Y.F. Luo]

I need to port pam_mkhome module to solaris, so first I have to make 
sure it  compiles under solaris,

so I did nothing but unzip, configure, make, then errors here:

...

Any idea? Actually any comment about porting pam_mkhome to solaris will 
be welcome.

Thanks.
