GCC 14 has enabled various warnings as errors by default, e.g. -Wimplicit-function-declaration. This causes the current feature detection code for `open_memstream(3)` and `fmemopen(3)` to fail with GCC 14. This commit restores compatibility with GCC 14 in this regard. Note that it may also be beneficial to pass a feature test macro such as -D_POSIX_C_SOURCE. See the feature test macro requirements for open_memstream(3)` and `fmemopen(3)`.
