Fred L. Drake, Jr. d1df594ca2 If the check library is not available, use an abbreviated implementation of
the check API.  This allows the unit and regression tests to be run on any
system without requiring an external package.

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.
