Peter Eisentraut 0869ea43e9 Remove flex version checks ... Remove the flex version checks from configure and meson. The cutoff versions are all so ancient that this is no longer relevant, and what the actual cutoff should be is a bit fuzzy. This also removes the ancient behavior that configure would also accept a "lex" program if it is actuall flex. This aligns the check with meson in this respect. For future reference, as of this commit, these are relevant flex versions: - The hard required minimum is flex 2.5.34 as of commit b1ef48980d, but this has not actually been tested. - Prior to this, the minimum enforced by configure/meson was flex 2.5.35, which is the oldest present in the buildfarm right now. - As of commit 6fdd5d9563, the oldest version that will compile without warnings due to flex-generated code is flex 2.5.36. - The oldest version that probably still has some practical relevance is flex 2.5.37, which ships with CentOS/RHEL 7.
