When I was building Perl I noticed a strange message​:

  You seem not to have gcc 4.x or later, not adding -D_FORTIFY_SOURCE.

But I had GCC 8.2. Reading Configure script I found​:

  case "$gccversion" in
  [4567].*) ... ...

So it seems the Configure script doesn't know GCC 8.x at all :(.

From @Tux

When I was building Perl I noticed a strange message​:

You seem not to have gcc 4\.x or later\, not adding \-D\_FORTIFY\_SOURCE\.

But I had GCC 8.2. Reading Configure script I found​:

case "$gccversion" in
\[4567\]\.\*\)    \.\.\. \.\.\.

So it seems the Configure script doesn't know GCC 8.x at all :(.

Fixed in

Xi Ruoyao​:

Can you build Perl 5 blead and let us know if Tux's patch has fixed your problem?

Thank you very much.
