| dnl Get the version number of Expat, using m4's esyscmd() command to run |
| dnl the command at m4-generation time. This allows us to create an m4 |
| dnl symbol holding the correct version number. AC_INIT() requires the |
| dnl version number at m4-time, rather than when ./configure is run, so |
| dnl all this must happen as part of m4, not as part of the shell code |
| dnl contained in ./configure. |
| dnl |
| dnl NOTE: esyscmd() is a GNU M4 extension. Thus, we wrap it in an appropriate |
| dnl test. I believe this test will work, but I don't have a place with non- |
| dnl GNU M4 to test it right now. |
