On gcc-10 `./configure` can't detect correct value of `-D_FORTIFY_SOURCE=`: ``` $ ./configure ... checking for GCC 3 or later... auto/configure: line 14735: test: 10.0.1: integer expression expected no checking whether we need -D_FORTIFY_SOURCE=1... auto/configure: line 14745: test: 10.0.1: integer expression expected no ``` ``` $ gcc -dumpversion 10.0.1 ``` It was noticed as vim buffer overflow detection as gentoo default to `-D_FORTIFY_SOURCE=2`: https://bugs.gentoo.org/706324#c2 The fix extends sed regex to catch multiple digits in major version.
