New Revision: 1521
Log:
Replaced CFLAGS with AM_CFLAGS and removed -g -O2.
Autoconf sets "-g -O2" automatically for CFLAGS, when no CFLAGS are given
during configure (provided gcc is available, otherwise only "-g" is used).
This way, packagers can decide what level of optimization they want.
The benefit of setting our own flags in AM_CFLAGS is that it obsoletes the
crutch of having CFLAGS substitution in CFLAGS itself. According to the
manual, CFLAGS is reserved for the user (i.e. packager), whereas AM_CFLAGS is
supposed to have flags that are deemed mandatory by the programmers.
