Building arts

When building arts in my new build environment I notice the following messages when building. I don't know whether the messages are harmless or meaningful. (repeats several times with different line numbers) ltdl.c: In function 'sys_dl_open': ltdl.c:605: warning: unused parameter 'loader_data' (repeats many times with different line numbers) gslmath.c:1005: warning: suggest explicit braces to avoid ambiguous 'else' (repeats many times with different line numbers) gsloscillator-aux.c:37: warning: unused parameter 'ifreq' gsloscillator-aux.c:38: warning: unused parameter 'mod_in' gsloscillator-aux.c:39: warning: unused parameter 'sync_in' gsloscillator-aux.c:40: warning: unused parameter 'pwm_in' (repeats several times) libtool: link: warning: `/usr/lib/gcc/i486-slackware-linux/4.2.4/../../../libstdc++.la' seems to be moved (the file exists at /usr/lib/libstdc++.la so I don't know what is checking in that directory.) The package compiles and the package size seems reasonable. Package contents are the same as the original stock 3.5.10 package. Darrell
