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