Q1: How do I specify that I want optimizations turned off? a) in Makefile.am: AM_CFLAGS = -O0 b) in configure.ac: CFLAGS="$CFLAGS -O0" c) other Q2: Does your answer for Q1 work even when I use AC_PROG_CC which places -02 in CFLAGS? Q3: Does your answer for Q1 violate this autotools principle: You should never redefine a user variable such as CFLAGS (http://tinyurl.com/3wkfdp5) Q4: Does AC_PROG_CC violate this principle?
