If using a GCC compiler, the dialect is -std=gnuXX where XX is the latest year supported by the compiler. In order these are: gnu89 gnu90, gnu9x, gnu99, gnu11, gnu1x, gnu17, gnu18, gnu19, gnu20, gnu2x
This also happens to be the default if you do not specify -std The Source Code does NOT contain #ifdef's to "turn off" GNU extensions when a GNU compiler is being used, so if you are using a GNU compiler you MUST use it in a GNU compliant mode. The actual version that is required when using a GNU compiler is probably gnu89, that is, ANSI C with GNU extensions. -- The fact that there's a Highway to Hell but only a Stairway to Heaven says a lot about anticipated traffic volume. >-----Original Message----- >From: sqlite-users <sqlite-users-boun...@mailinglists.sqlite.org> On >Behalf Of Dennis Clarke >Sent: Tuesday, 19 November, 2019 06:29 >To: sqlite-users@mailinglists.sqlite.org >Subject: Re: [sqlite] What is the C language standard to which sqlite >conforms ? > >On 11/19/19 12:32 AM, Scott Robison wrote: >> On Mon, Nov 18, 2019 at 3:44 PM Dennis Clarke <dcla...@blastwave.org> >wrote: >> >>> >>> Same question as a few days ago. >>> >>> This may have been asked many times before but always seems to be a >>> valid question.
