# The "-B$libc/lib/" flag is a quick hack to force gcc to link |

# against the crt1.o from our own glibc, rather than the one in |

||||
# compiler/linker, i.e., one that searches /usr/lib and so on.) |

# |

# Unfortunately, setting -B appears to override the default search |
||||
# path. Thus, the gcc-specific "../includes-fixed" directory is |
||||
# now longer searched and glibc's <limits.h> header fails to |
||||
# compile, because it uses "#include_next <limits.h>" to find the |

# limits.h file in ../includes-fixed. To remedy the problem, |

# another -idirafter is necessary to add that directory again. |
