| 8 | dnl ------------------------------------------------- |
| 9 | dnl Placing a call to this macro in configure.ac after |
| 10 | dnl the one to AC_INIT will make macros in this file |
| 11 | dnl visible to the rest of the compilation overriding |
| 12 | dnl those from Autoconf. |

| 19 | dnl Override some Libtool tests |
| 20 | dnl ------------------------------------------------- |
| 21 | dnl This is done to prevent Libtool 1.5.X from doing |
| 22 | dnl unnecesary C++, Fortran and Java tests and reduce |
| 23 | dnl resulting configure script by nearly 300 Kb. |

| 30 | dnl ------------------------------------------------- |
| 31 | dnl This is done to prevent compiler warning |
| 32 | dnl 'function declaration isn't a prototype' |
| 33 | dnl in function main. This requires at least |
| 34 | dnl a c89 compiler and does not suport K&R. |

| 48 | dnl embedded comments that hit the resulting script |
| 49 | dnl removed. This is done to reduce configure size |

| 91 | dnl allow us to use this macro early enough in the |
