1 | dnl Expat macro retrived on the Expat CVS |
| 2 | ||
| 3 | dnl Check if --with-expat[=PREFIX] is specified and | |
| 4 | dnl Expat >= 1.95.0 is installed in the system. | |
| 5 | dnl If yes, substitute EXPAT_CFLAGS, EXPAT_LIBS with regard to | |
| 6 | dnl the specified PREFIX and set with_expat to PREFIX, or 'yes' if PREFIX | |
| 7 | dnl has not been specified. Also HAVE_LIBEXPAT, HAVE_EXPAT_H are defined. | |
| 8 | dnl If --with-expat has not been specified, set with_expat to 'no'. | |
| 9 | dnl In addition, an Automake conditional EXPAT_INSTALLED is set accordingly. | |
| 10 | dnl This is necessary to adapt a whole lot of packages that have expat | |
| 11 | dnl bundled as a static library. | |
