Subject: [PATCH] fix(swig): avoid clang GNUC pragma block before _lib.h
Clang defines __GNUC__, so the old guard emitted PRAGMA_* tokens before
they were defined, breaking builds on macOS/clang; move the block after
<_lib.h> and exclude clang while keeping the GCC<5 workaround.
Fixes: https://todo.sr.ht/~mcepl/m2crypto/392
Upstream-Status: Backport [git.sr.ht/~mcepl/m2crypto/commit/504ca8f438afb0f5041d2b5163e5f666a9a1b742.patch]
