[PATCH 0/2] Fix doxygen build failure caused by bugs in flex

[Leo Famulari]

Doxygen fails to build on core-updates, like this:

------
[ 26%] [FLEX][scanner] Building scanner with flex 2.6.2
cd /tmp/guix-build-doxygen-1.8.11.drv-0/doxygen-1.8.11/src &&

make[1]: *** [CMakeFiles/Makefile2:257: src/CMakeFiles/_doxygen.dir/all] Error 2
make[1]: *** Waiting for unfinished jobs....
------

Because doxygen builds fine with flex 2.6.3, I think it's related to
bugs in flex, which are mentioned in the flex 2.6.3 release notes:

https://github.com/westes/flex/commit/581ef6d17f7fccc9c538c0f0bda9b89df66c2dc3#diff-ff4e2dc4962dc25a1512353299992c8dR8

Leo Famulari (2):
  gnu: flex: Update to 2.6.3.
  gnu: doxygen: Update to 1.8.13.
