[Nut-upsdev] Fwd: m4 scripts ignore user-supplied CFLAGS and LDFLAGS
Hi Alexander, no, I am not responsible for this! It's true that I created the scripts in m4/, but I only copied what was previously in configure.in. Try: svn up -r2 configure.in and you'll see that the code in question has been there since the beginning of SVN time (line 175). I cannot say why it was done that way. Probably because nobody needed a more general mechanism. Using pkgconfig seems like a good idea, but there should be a fallback method if pkgconfig is not installed or does not work. I think some of our autoconf tests already do something like this. -- Peter Alexander I.
