Mike,

This is usually occures when the compiler comes across a variable 
declaration that uses a data type that the compiler hasn't "seen" yet.  In 
this case, it appears that the compiler doesn't know what a "stat" type is, 
so when it comes to a line that tries to create a variable of "stat" type, 
like this:

        struct stat stbuf;

it does know how to create the stbuf variable.  If it didn't complain about 
not being able to find a header file (which is where these data types are 
usually defined), then it is possible that the header file that is 
available doesn't have this definition in it.

Here is a recommended starting place for your search for an answer.  Go to 
a command line and type:

        man stat

I think this relates to your problem.  The stat() function is in the header 
file /usr/include/sys/stat.h and this file pulls in 
/usr/include/bits/stat.h, which is the file that has the "struct stat" 
definition in it.  You should check to see if you have these two files.  If 
you do, then you will have to figure out why the compiler doesn't see them.

Good luck,

Wes
