Also with USE="-debug" i see: x86_64-pc-linux-gnu-gcc -march=native -O2 -g0 -Wl,-O1 -Wl,--as-needed -Wl,--hash-style=gnu -I. -I../include -I/usr//include -I/usr/include/mysql -DHAVE_CONFIG_H -DARGUS_SYSLOG -g -c ./argus_main.c Please drop.
Even /with/ USE=debug it should not be doing that. Oddly enough acsite.m4 says -g is only added to CFLAGS when a file named .devel is present, so injecting CFLAGS into any Makefile.in as it was done since bug #331871 was the wrong solution. I think I have it fixed now in 3.0.4.1-r2 and 3.0.5.16.
