Using the GNU Compiler Collection (GCC)

10.1 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.

• When `-pedantic-errors' is specified, GCC will incorrectly give an error message when a function name is specified in an expression involving the comma operator.
