For debug builds:
./configure CFLAGS='-g' CPPFLAGS=-D__MY_DEBUG__
For regular builds:
./configure
If you use assert.h, you can also speed things up a bit more by turning
off the assertions with:
./configure CPPFLAGS=-DNDEBUG
Of course you can write (or find and copy) some Autoconf M4 code to
do some or all of the above automatically depending on the presence
of configure options like:
./configure --enable-debug
Googling for 'AC_ARG_ENABLE debug' turns up many examples such as:
AC_ARG_ENABLE([debug],
[ --enable-debug build with additional debugging code],
[CFLAGS='-g';AC_DEFINE([__MY_DEBUG__])])
