> CPPFLAGS=-I/usr/local/include ./configure
Bzzt. Please pass variable settings as arguments to configure:
./configure CPPFLAGS=-I/usr/local/include
not as environment variables. It has the advantage that
./config.status --recheck
(which may be triggered from a makefile) remembers such settings
*even* if the variables in question are not marked as precious by
configure.ac. (CPPFLAGS is markes as precious by AC_PROG_CC, but
better get the "new-since 10 years" way of doing it in your head
now ;-)
True true! Sadly I encounter old programs that still don't grok this;
so it is kinda hardwired into my brain. :-(
