dnl Ensure that Expat is configured with autoconf 2.52 or newer
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.
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.
