Builds are broken on MacOS 15.4

[vtorikianupgrade]

Following the update to MacOS 15.4 build/tests are broken:

$ go test ./...
# github.com/pganalyze/pg_query_go/v6/parser
src_port_snprintf.c:374:1: error: static declaration of 'strchrnul' follows non-static declaration

I have found the same issue seems to be present upstream on the pgsql mailing list: https://www.postgresql.org/message-id/385134.1743523038%40sss.pgh.pa.us.

Potential upstream fix: postgres/postgres@6da2ba1

Looks like an upstream fix for libpg_query is up in a branch, not yet released/tagged tho

Iv'e opened #133 which is my temporary fix. Feel free to use or ignore it, I thought I'd share what worked for me. :)

I'm using this via:

replace (
	github.com/pganalyze/pg_query_go/v6 v6.0.0 => github.com/skandragon/pg_query_go/v6 v6.0.0-20250402183148-7fdb0f388997
)

I run the following as a quickfix:

export CGO_CFLAGS="-DHAVE_STRCHRNUL -mmacosx-version-min=15.4" MACOSX_DEPLOYMENT_TARGET=15.4

The 2nd flag and latter env var are optional, they're only for removing the warning.

Resolved in v6.1.0 - thanks for the report!

Please report back in case there are still any issues with the build.
