This tests the patch for PR34975, in which 'n', 'ipol', and 'i' would be +! determined to have 'no IMPLICIT type'. It turned out to be fiendishly +! difficult to write a testcase for this PR because even the smallest changes +! would make the bug disappear. This is the testcase provided in the PR, except +! that all the modules are put in 'use_only_3.inc' in the same order as the +! makefile. Even this has an effect; only 'n' is now determined to be +! improperly typed. All this is due to the richness of the symtree and the +! way in which the renaming inserted new symtree entries. Unless somenody can +! come up with a reduced version, this relatively large file will have to be added +! to the testsuite. Fortunately, it only has to be comiled once:) +! +!
