Subject: [Ada] Check token to be "access", reject it if not
Date: Tue, 17 May 2022 08:27:28 +0000	[thread overview]
Message-ID: <20220517082728.GA1087423@adacore.com> (raw)

[-- Attachment #1: Type: text/plain, Size: 243 bytes --]

The parser skips the token without verifying it is indeed "access".  So
any token is accepted.

Tested on x86_64-pc-linux-gnu, committed on trunk

gcc/ada/

	* par-ch3.adb (P_Access_Type_Definition): Outputs an error if
	token is not "access".
