The ssp headers are meant to be used together with -D_FORTIFY_SOURCE{,=2}
-isystem .../include/ssp/
They are meant to override the system stdio.h, string.h and/or unistd.h
headers, which they include as #include_next.
So this looks like a user error, or maybe NetBSD header bug.
Of course, if _FORTIFY_SOURCE support is in your C library, you don't need any
of the libssp headers.

Correct includes for libssp

This gets me a bit further, but I still have trouble using it.

For netbsd we have in stdio.h:
 #if _FORTIFY_SOURCE > 0
 #include 
 #endif

for non-netbsd, you can likely achieve the same failure by attempting
to compile this code:
 #define _FORTIFY_SOURCE
 #include 
 #include 
 void main() { printf("Hello!"); }
