explains why you should rather assign the awk script output to an
intermediate variable (including M4 quoting):
  version=`awk '/MAJOR/ {major="$[3]"} END {printf "%d\n", major}' module.h`
  AC_CONFIG_COMMANDS([version.h], [echo "version is $version" > version.h])

Also, please do not post the same question independently to several
lists, thanks.

Cheers,
Ralf
