* Makefile.in (CFILES): Add safe-ctype.c. (REQUIRED_OFILES): Add safe-ctype.o. * argv.c: Define ISBLANK and use it, not isspace. * basename.c, cplus-dem.c, fnmatch.c, pexecute.c, strtod.c, strtol.c, strtoul.c: Include safe-ctype.h, not ctype.h. Use uppercase ctype macros. Don't test ISUPPER(c)/ISLOWER(c) before calling TOLOWER(c)/TOUPPER(c).binutils-2_11-branch

with the following properties: |

|

- Implements all isxxx() macros required by C99. |

- Also implements some character classes useful when |

parsing C-like languages. |

- Does not change behavior depending on the current locale. |

- Behaves properly for all values in the range of a signed or |
