[Source compatibility suite] GDRB failing to build older revisions - error: cannot find 'strcmp' in scope

[justice-adams-apple]

Description

GRDB is failing to build with older revisions after the SDK update with the following error:

GRDB.swift/GRDB/Core/StatementAuthorizer.swift:99:19: error: cannot find 'strcmp' in scope
 97 |             // are prevented when the truncate optimization is disabled.
 98 |             // Let's authorize such deletions by returning SQLITE_OK:
 99 |             guard strcmp(cString1, "sqlite_master") != 0 else { return SQLITE_OK }
    |                   `- error: cannot find 'strcmp' in scope
100 |             guard strcmp(cString1, "sqlite_temp_master") != 0 else { return SQLITE_OK }

This is failing to build with the listed 4.2, 5.1, 5.3, 5.7 revisions of the project

Reproduction

swift build --disable-sandbox --package-path GRDB.swift --verbose --configuration debug --build-tests -Xswiftc -swift-version -Xswiftc 5 -Xswiftc -enable-testing

Expected behavior

Expected to build properly

Environment

Apple Swift version 6.2-dev (LLVM 3a02857b159678d, Swift c91e295)
Target: x86_64-apple-macosx13.0

[groue]

For what's worth, this strcmp issue went unnoticed in previous Swift releases.

Since the breaking change has been shipped, GRDB has been modified multiple times in order to fix the reported issue:

• groue/GRDB.swift@344878c
• groue/GRDB.swift@fcfdab2
• groue/GRDB.swift@77a4d17

(Note that I find the use of strcmp justified, since we're dealing with C strings).
