in thread Config sets optimisation compilation flags (-O/-g)!

Config basically tells you what flags the perl executable was built with, or more to the point, what flags XS code needs to be compiled with in order to work seamlessly with the perl interpreter. The flags are determined by the arguments to Configure plus whatever probes and/or decisions Configure makes. If you don't like the flags, build a perl with different flags. If you want to debug, build a debugging perl with ./Configure -DDEBUGGING

    OK got that. So, FORTIFY_SOURCE was used when building my perl. I am used to pkg-config which tells you how to compile and link as opposed to Config which tells you how perl was built. Fine.
