Actual Bugs We Haven't Fixed Yet

• The fixincludes script interacts badly with automounters; if the directory of system header files is automounted, it tends to be unmounted while fixincludes is running. This would seem to be a bug in the automounter. We don't know any good way to work around it.
• The fixproto script will sometimes add prototypes for the sigsetjmp and siglongjmp functions that reference the jmp_buf type before that type is defined. To work around this, edit the offending file and place the typedef in front of the prototypes.
• There are several obscure case of mis-using struct, union, and enum tags that are not detected as errors by the compiler.
• When `-pedantic-errors' is specified, GNU C will incorrectly give an error message when a function name is specified in an expression involving the comma operator.
• Loop unrolling doesn't work properly for certain C++ programs. This is a bug in the C++ front end. It sometimes emits incorrect debug info, and the loop unrolling code is unable to recover from this error.
