The first of these problems is longstanding: if an error-less B.h is included from error-ridden A.h, flymake's legacy parser will panic (and disable itself) since it sees a non-zero exit for a clean file. To fix this, recommend returning 'true' in the documentation for the check-syntax target. Another problem was introduced by the parser rewrite. For error patterns spanning more than one line, point may be left in the middle of a line and thus render other patterns useless. Those patterns were written for the old line-by-line parser. To make them useful again, move to the beginning of line in those situations. The third problem was also longstanding and happened on newer GCC's: The "In file included from" prefix confused flymake-proc-get-real-file-name. Fix this. Also updated flymake--diag-region to fallback to highlighting a full line less often. Add automatic tests to check this. * lisp/progmodes/flymake-proc.el (flymake-proc--diagnostics-for-pattern): Fix bug when patterns accidentally spans more than one line. Don't create diagnostics without error messages. (flymake-proc-real-file-name-considering-includes): New helper. (flymake-proc-allowed-file-name-masks): Use it. * lisp/progmodes/flymake.el (flymake-diag-region): Make COL argument explicitly optional. Only fall back to full line in extreme cases. * test/lisp/progmodes/flymake-tests.el (included-c-header-files): New test. (different-diagnostic-types): Update. * test/lisp/progmodes/flymake-resources/Makefile (check-syntax): Always return success (0) error code. (CC_OPTS): Add -Wextra * test/lisp/progmodes/flymake-resources/errors-and-warnings.c (main): Rewrite comments. * test/lisp/progmodes/flymake-resources/errors-and-warnings.c: Include some dummy header files. * test/lisp/progmodes/flymake-resources/no-problems.h: New file. * test/lisp/progmodes/flymake-resources/some-problems.h: New file. * doc/misc/flymake.texi (Example---Configuring a tool called via make): Recommend adding "|| true" to the check-syntax target.
