Dear Classpath-members,
after my last update of the Classpath sources I detected some parameters of functions which are unused and are marked by
__attribute__ ((__unused__)
Unfortunatelly this is not portable to some non-GNU compilers (as I know... at least I have one C-compiler for ARM which can not handle this). Can we use a macro for this? E. g.
#ifdef __GNUC__ #define VARIABLE_ATTRIBUTE_UNUSED __attribute__ ((__unused__)) #else #define VARIABLE_ATTRIBUTE_UNUSED #endif
A configure-test would also be possible instead "#ifdef __GNUC__".
Another idea would be some construct of the form
if ((parameter)==(parameter));
for each unused parameter. This would avoid a C-compiler warning for still not implemented functions and keep the prototypes clean (implemenation later will become simpler, because the header files do not change).
By,
Torsten
