cups makefiles do honor CFLAGS, so GARFLAVOR = DBG, I can see that the
flag -g is present in compiler invocations.

Using ALL_CFLAGS=-I.. -D_CUPS_SOURCE -I/usr/include/kerberosv5
-I/export/home/blizinski/build.5.10-i386/opt/csw/include

Using LIBS=-lcups -lssl -lcrypto -lpthread -lresolv -lnsl -lsocket -lm

The binary is in fact not stripped:

$ file cups-polld
cups-polld:     ELF 32-bit LSB executable 80386 Version 1 [FPU],
dynamically linked, not stripped

However, it doesn't seem to be compiled without optimization: when I
run it under the Sun Studio debugger, and display the call stack, I
see:

main(argc = ???, argv = ???) (optimized)

Is there a way to check whether the binary is actually optimized
during compilation?
