Description

zsh might hang waiting for subprocess when build with clang-16 or gcc-14.

Step to reproduce:

  1. execute zsh -c "echo $(whoami)"
  2. try send SIGTERM to zsh, nothing response.

Workaround:

Add -Wno-error=implicit-int to CFLAGS during configure, or

pick commit ab4d62e("50641: use 'int main()' in test C-codes in configure") from upstream.

Thanks for the report. I'll go with the extra compiler flag.

zsh: Run configure tests more leniently

Several configure tests fail because recent compilers error out on
functions with missing type specifiers. The resulting shell hangs
indefinitely in certain circumstances.

Suppress the "implicit-int" compiler error during configure. Upstream
has added explicit type specifiers to the configure functions, so the
next release will fix this issue properly.
