Let's try to go through them one by one (in different replies).

OK, this version of flex is ~ 15 years old, and ...

... doesn't support the '--header-file' option. This issue has been
reported once already (in automake bug#12836, which I am CC:ing).
The patch should take care of the issue. Can you confirm it works?

Subject: [PATCH] tests: fix a spurious failure with older flex versions
See automake bug#11524 and bug#12836.
* t/lex-header.sh: Here, we use flex option '--header-file',
but that option is not supported by some older flex versions.
Simply skip this test if such an old flex version is detected.
