System: OSF1 korsakov V4.0 1229 alpha
Machine: alpha
	
host: alphaev67-dec-osf4.0f
build: alphaev67-dec-osf4.0f
target: alphaev67-dec-osf4.0f
configured with: /vol/gnu/src/gcc/gcc-dist/configure --prefix=/vol/gcc --with-local-prefix=/vol/gcc --disable-nls --enable-libgcj alphaev67-dec-osf4.0f
>Description:
libgcj fails to compile on this target:

/vol/gnu/src/gcc/gcc-dist/libjava/java/lang/natClassLoader.cc: In function 
   `void _Jv_RegisterClassHookDefault(java::lang::Class*)':
/vol/gnu/src/gcc/gcc-dist/libjava/java/lang/natClassLoader.cc:468: `snprintf' 
   undeclared (first use this function)
/vol/gnu/src/gcc/gcc-dist/libjava/java/lang/natClassLoader.cc:468: (Each 
   undeclared identifier is reported only once for each function it appears 
   in.)

Tru64 UNIX V4.0 (as well as e.g. IRIX 6.2 and Solaris 2.5.1) lacks snprintf in
libc.  libgcj should still be usable on such platforms.
	
>How-To-Repeat:
Bootstrap gcc with --enable-libgcj.
	
>Fix:
Use sprintf with a format (like %.170s or some such) to avoid buffer overflows.
