Subject: host-cpu-c-abi: recognize i386 and a couple of other CPUs as 32-bit
Date: Sun, 27 Oct 2019 15:37:22 +0100	[thread overview]
Message-ID: <2016948.EaZPAPkSUT@omega> (raw)

This patch fixes a mistake, by which gl_HOST_CPU_C_ABI_32BIT would fail
to recognize i386 as a 32-bit CPU.


2019-10-27  Bruno Haible  <bruno@clisp.org>

	host-cpu-c-abi: Recognize i386 and a couple of other CPUs as 32-bit.
	* m4/host-cpu-c-abi.m4 (gl_HOST_CPU_C_ABI): Include i386 in the case
	statement.
	(gl_HOST_CPU_C_ABI_32BIT): Likewise. Also recognize a couple of other
	32-bit CPUs.
