This was a problem as the code being ignored released a lock. When we found the problem we investigated what level would be needed to get a warning and found... leo:~/deleteme:22$ gcc -Wall yabt.c -o yabt leo:~/deleteme:23$ gcc -Wall -ansi yabt.c -o yabt leo:~/deleteme:24$ gcc -Wall -ansi -pedantic yabt.c -o yabt yabt.c:9: warning: text following `#endif' violates ANSI standard yabt.c:13: warning: text following `#endif' violates ANSI standard It seems there is no warning level lower than pedantic to show this, it would be nice if there were. Attached sample (erroneous) C code to demonstrate problem. The code that had the bug in has ... -Wall -Wno-unused -Wno-switch Wpointer-arith -Wredundant-decls -Wnested-externs -Winline -W -Werror turned on. >How-To-Repeat: Compile yabt.c with various warnings. Only get warned of ignored code with -pedantic >Fix: >Release-Note: >Audit-Trail: >Unformatted:
