+Subject: [PATCH] Make test_parsing more resilient to changes in
+ pycparser  (#224)
+
+* Make test_parsing more resilient to changes in pycparser
+
+Several tests expect precise error messages from pycparser, which pycparser
+doesn't guarantee. While testing CFFI with pycparser 3.0, some tests needed
+to be made more resilient. I've used the .startswith() approach already used
+in this file, instead of exact string matching.
+
+Ref #223
+
+* Loosen error message assertion even more
+
+Upstream-Status: Backport [https://github.com/python-cffi/cffi/commit/c36c02fa6f4f1d12a9cead81861c6f42af47da22]
