 // The purpose of this file is to glue the mismatching headers (Android NDK vs
 // glibc) and therefore avoid doing otherwise awkward #ifdefs in the code.
 // The following quirks are currently handled by this file:
+// - i386: Use the Android NDK but alias user_fxsr_struct > user_fpxregs_struct.
 // - aarch64: Add missing <stdint.h> include.
 // - Other platforms: Just use the Android NDK unchanged.
