+Subject: [PATCH] contrib/eggbitset: disable x64 code paths on 32-bit x86
+
+roaring.h enables USEAVX (and thus IS_X64) whenever __AVX2__ is defined,
+and USESSE4 whenever __POPCNT__ and __SSE4_2__ are defined.  This also
+happens on 32-bit x86 targets such as i686 built with -march=haswell,
+where 64-bit only intrinsics like _mm_popcnt_u64() and
+_mm256_extract_epi64() are not available, so the build fails with:
+
+  roaring.h:260:18: error: implicit declaration of function
+    '_mm_popcnt_u64'; did you mean '_mm_popcnt_u32'?
+    [-Wimplicit-function-declaration]
+  roaring.h:1011:23: error: implicit declaration of function
+    '_mm256_extract_epi64'; did you mean '_mm256_extract_epi8'?
+    [-Wimplicit-function-declaration]
+
+Define DISABLE_X64 from the build system when building for 32-bit x86 so
+that the portable implementation is used instead. This keeps the bundled
+CRoaring sources unmodified, making future updates a plain copy.
+DISABLE_X64 is only set for x86, as it also guards the NEON detection
+used on ARM.
