reduced test-case
The clang-cl compiler disallows C11 convenience macro static_assert in the
function scope. It does allow static_assert in the file scope.
This problem is also reported in
<a href="https://github.com/ionescu007/minlzma/issues/1">https://github.com/ionescu007/minlzma/issues/1</a>.
Here is a reduced test-case:
C:\src\build>clang-cl --version
clang version 12.0.0 (<a href="https://github.com/llvm/llvm-project/">https://github.com/llvm/llvm-project/</a>
6de4865545da73687dd6d28d153cd345ed5e7918)
Target: x86_64-pc-windows-msvc
Thread model: posix
InstalledDir: C:\src\chromium\src\third_party\llvm-build\Release+Asserts\bin
C:\src\build>type static-assert.c
#include <assert.h>
_Static_assert(1 == 1, "");
static_assert(1 == 1, "");
void Foo(void) {
_Static_assert(1 == 1, "");
static_assert(1 == 1, "");
}
C:\src\build>clang-cl /s static-assert.c
