// 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:
//   - NDK r10: Add missing user_regs_struct and user_fpsimd_struct structs.
//   - NDK r11+: Add missing <stdint.h> include
// - Other platforms: Just use the Android NDK unchanged.

// TODO(primiano): remove these changes after Chromium has stably rolled to
// an NDK with the appropriate fixes.
