2018-09-11Revert "Make versions of DIAG_OFF() and DIAG_ON() for GCC 4.2 through 4.5."Guy Harris1-72/+14
This reverts commit f6b8bc39c66c878ff25a4f48fff382f8775a2711. Reason for revert: prior to 4.6 or so, the pragmas didn't work as well, e.g. they couldn't be used inside a function; we depend on them being usable within a function.

2018-09-11Make versions of DIAG_OFF() and DIAG_ON() for GCC 4.2 through 4.5.Guy Harris1-14/+72

2018-09-09Revert "Try unconditionally using the pragmas in Clang."Guy Harris1-2/+2
This reverts commit 051efd105a8404093139dd4a54620c98c4ff170e. Reason for revert: The Clang on the macOS buildbot is 3.1, so it should have been using the _Pragmas; perhaps it "supports" them but they don't actually *work*, or perhaps something else is wrong.

This should test whether the macOS buildbot Clang really *does* support them, in which case we should use them, or not. Change-Id: I52b7b9c450b5f7ba09df72a56ddb91b5750196dc Reviewed-on: https://code.wireshark.org/review/29521 Reviewed-by: Guy Harris <guy@alum.mit.edu>

2018-05-13Suppress -Wshadow warnings in Bison-generated code.Guy Harris1-13/+13
Apparently, some versions of Bison also generate global generations of yylval, or its appropriately-prefixed equivalent, in pure parsers. Suppress -Wshadow in Bison-generated code as well as Berkeley YACC-generated code.

2018-02-28Squelch some Visual Studio Code Analyzer warnings in Flex-generated scanners.Guy Harris1-1/+14
Hopefully this filters out stuff about which we can't do very much (other than send off a Flex fix and wait for it to be accepted and end up in a WinFlexBison package), making it easier to find the stuff about which we *can* directly do something (i.e., problems in code *we* wrote).

2018-02-24Suppress some warnings caused by a Berkeley YACC bug/misfeature.Guy Harris1-0/+29
Berkeley YACC generates a global declaration of yylval, or the appropriately prefixed version of yylval, in the .h file, *even though it's been told to generate a pure parser, meaning it doesn't have any global variables*. Bison doesn't do this. That causes a warning due to the local declaration in the parser shadowing the global declaration. So, if this is Berkeley YACC, and we have _Pragma, and have pragmas to suppress diagnostics, we use it to turn off -Wshadow warnings.

Don't explicitly use #pragma to turn off warnings; use DIAG_OFF_FLEX for all of them. If we use DIAG_OFF_FLEX, use DIAG_ON_FLEX, even if we have no section of entirely included code at the end.

DIAG_OFF_FLEX turns off all warnings that we want to disable for Flex-generated code due to some versions of Flex generating code that triggers those warnings. DIAG_ON_FLEX restores those warnings, so we do the checks for code that *we* wrote. Use them in .l files.

2017-10-27Clean up a bit.Guy Harris1-24/+31
If we're using Clang, use either _Pragma("clang diagnostic XXX") or nothing; don't use _Pragma("GCC diagnostic XXX"). If we're using something other than Clang that is, or claims to be, GCC, use _Pragma("GCC diagnostic XXX") or nothing. Explain why we're only using _Pragma("GCC diagnostic XXX") with GCC 4.8 or later, even though it's supported in GCC 4.2 and later, and even though 4.6 an later support _Pragma("GCC diagnostic {push,pop}").
