gcc 4.8 compiler warning in ecpg check

With gcc 4.8, I get a compiler warning when building the ecpg test
files:

define.pgc: In function 'main':
define.pgc:21:19: warning: typedef 'string' locally defined but not used [-Wunused-local-typedefs] typedef char
string[NAMELEN];                 ^
 

This could be removed, but is it something that is actually part of what
is being tested?
