In gawk-5.2, a feature that allows gawk to preserve memory between runs: https://www.gnu.org/software/gawk/manual/html_node/Persistent-Memory.html was added. The files that implement this, support/pma.[ch], are licensed under the AGPL3 which some entities perfer to avoid. Force people to knowingly opt into using this feature and license using: PACKAGECONFIG:append:pn-gawk = " pma-if-64bit" where pma is an abbreviation for persistent memory allocator and the "-if-64bit" suffix is a indicator to users that the feature only works for 64 bit targets. Also add AGPL to LICENSE and LICENSE:${PN}, when using pma. Correct the license to be AGPL-3.0-or-later. There hasn't been a change in the license terms, at least for main.c, haven't changed significantly in the last 15 years: License-Update: Reflects conditional AGPL use and more as described above. Testing requires a non-root account and following the example in the link above: $ truncate -s <size> data.pma $ chmod 0600 data.pma $ GAWK_PERSIST_FILE=data.pma gawk 'BEGIN { print ++i }' 1 $ GAWK_PERSIST_FILE=data.pma gawk 'BEGIN { print ++i }' 2 $ GAWK_PERSIST_FILE=data.pma gawk 'BEGIN { print ++i }' 3 This works on qemu[x86-|arm|riscv]64 but not on qemu[arm|x86] where the --enable-pma is ignored because there is a requirement and build-time test for 8 byte void pointers in m4/pma.m4: if test "$SKIP_PERSIST_MALLOC" = no && test $ac_cv_sizeof_void_p -eq 8 Finally, remove an old comment about GPLv2, GPLv3 versions of gawk since this is no longer important as the GPLv2 version is not maintained.
