Here is an experimental change to support the feature.

I looked at it but we probably need to rework/update the entire libtool stuff which has a high regression risk. Thus I give this bug a low priority because it is not a functional bug.

doc/HACKING says it's OK to use variadic arg macros (from C99 features).
If it's OK, this patch can fix the initialization (which silences GCC 15 warnings):

Note that 1.53 was released today which fixes a small regression:

In case of build problems related to a failed test you may want to apply rEb6df311368133df90c3bf338fbf5c90bd8d950f8.

Fixed in: rE0f4fe2edf5e5: spawn: Care about closefrom/close call is interrupted.

@werner I read the code of gpgme/src/posix-io.c. I understand the two points:

• For the correctness sake, the possible interrupted closefrom should be handled.
• we can share the code with closefrom case and non-closefrom case.

@gniibe: Please see gpgme/src/posix-io.c where we have this:

Thank you for your report.

Fixed in rA69069bc63e6b: Remove an declaration for an unused function.

Hm, this might also be relevant in GnuPG's codebase in common/exechelp-posix.c, which contains a copy of the same code (licensed differently).

This problem has gone in libgpg-error 1.51, since the implementation doesn't use environ any more.

Fixed in 1.51, by introducing gpgrt_spawn_actions_set_env_rev, which assumes utf-8 encoding.

Fixed in 1.51.

Fixed in 1.51.
