dnl Placing a call to this macro in configure.ac after |
|
dnl the one to AC_INIT will make macros in this file |
|
dnl visible to the rest of the compilation overriding |
|
dnl those from Autoconf. |

dnl Override some Libtool tests |
|
dnl ------------------------------------------------- |

dnl This is done to prevent Libtool 1.5.X from doing |

dnl unnecesary C++, Fortran and Java tests and reduce |
|
dnl resulting configure script by nearly 300 Kb. |

dnl in function main. This requires at least |
|
dnl a c89 compiler and does not suport K&R. |
