-Subject: [PATCH] Define _POSIX_C_SOURCE for crfsuite source files
-
-gcc-14 has "-Werror=implicit-function-declaration" enabled by default.
-crfsuite uses posix_memalign which only gets defined when _POSIX_C_SOURCE is
-defined, so make sure the flag is set when compiling crfsuite.
-
-On the other hand, openSUSE Tumbleweed has _POSIX_C_SOURCE defined
-in pyconfig.h, so you must not add "-D_POSIX_C_SOURCE" when compiling
-the python binding source code. So add it only for the subdir crfsuite.
