[Gard Spreemann]

Package: librust-bindgen-dev
X-Debbugs-Cc: gspr at nonempty.org
Version: 0.59.2-2+b1
Severity: normal

Dear Maintainer,

Bindgen fails to generate bindings for C code that includes SSE
intrinsics headers like emmintrin.h:

  /usr/lib/llvm-13/lib/clang/13.0.1/include/emmintrin.h:2374:10: error: invalid conversion between vector type '__m128i' (vector of 2 'long long' values) and integer type 'int' of different size

This bug report is meant as documentation, as it seems that 0.60.1
(already in sid) fixes the issue.
