"checking whether Boost.Process can be used" fails with Boost 1.88.0

Inizia con il controllo di Boost.Process intorno alla riga 35973 di configure, usando il config.log allegato, e confrontalo con la macro di rilevamento AX_BOOST_PROCESS. Riproduci il problema con Boost 1.88.0 e --enable-external-signer. Il lavoro è completato quando la configurazione accetta Boost 1.88.0 e la firma esterna è abilitata senza il fallimento dovuto alla libreria di collegamento mancante.

checking for boostlib >= 1.64.0 (106400)... yes
checking whether Boost.Process can be used... no
configure: error: External signing is not supported for this Boost version

configure:36004: result: no
configure:36013: error: External signing is not supported for this Boost version

Expected behavior

Boost 1.88.0 should be accepted as a usable version of Boost when enabling external-signer.

Actual behavior

Configure rejects Boost 1.88.0 due to a missing link library.

To reproduce

Upgrade to Boost 1.88.0. Try to configure Elements with --enable-external-signer.

System information

Elements 23.3.1rc2

Linux 6.12.41-gentoo x86_64

Note that there is an AX_BOOST_PROCESS macro that theoretically could be used here, but it also fails to detect Boost::Process, as it appears to be attempting to use a class declared in the deprecated Process v1 headers without actually including those headers.
