[Autoconf-patches] Support for nested AT_DATA

[Pavel Roskin]

Hello!

Currently it's impossible to use AT_DATA in the configure.in scripts used
in AT_TEST_MACRO. The problem is that AT_DATA always uses the same file
delimiter - EOF.

This patch makes AT_DATA generate the delimiter based on the file being
created, so that the shell doesn't get confused by overlapping EOF's. Now
I can e.g. create a "mycpp" script in AT_TEST_MACRO using AT_DATA.
