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.
