[Bruno Haible]

This implements a small optimization.

2007-01-26  Bruno Haible  <address@hidden>

        Small optimization.
        * lib/javacomp.c: Include c-strstr.h.
         (is_envjavac_gcj): Use c_strstr instead of strstr.
        * modules/javacomp (Depends-on): Add c-strstr, remove strstr.
