Well, C99 mode can help 'stdbool' on some platforms, but not on others. Citing doc/posix-headers/stdbool.texi: This header file is missing on some platforms: AIX 5.1, HP-UX 11, IRIX 6.5, OSF/1 5.1. On HP-UX it may help, but on the other three platforms, asking the compiler for more C99 compliance won't make an stdbool.h appear on the file system.
