I was looking through my logs to identify which packages do not use
my CFLAGS, CXXFLAGS (thinking about trying LTO at some point) and
reading the voluminous output from perl's Configure I noticed:
Guessing which symbols your C compiler and preprocessor define...
You seem not to have gcc 4.* or later, not adding -D_FORTIFY_SOURCE.
That is because 5.28.1 has the following:
case "$gccversion" in
[4567].*) case "$optimize$ccflags" in
Using
sed -i 's/^\(\[4567\)/\18/' Configure
gives me
Guessing which symbols your C compiler and preprocessor define...
Adding -D_FORTIFY_SOURCE=2 to ccflags...
