Hi all,
In version 5.7.10, I found a C++ comment in the .h headers:
#endif // __cplusplus
Should be:
#endif /* __cplusplus */
To avoid:
cc -g -fsanitize=address -fno-omit-frame-pointer -W -Wall -pedantic
-Wmissing-prototypes \
-Wno-long-long -Werror -fPIC \
-I/opt3/dbs/mys/5.7
To endow CREATE VIEW with COMMENT would be splendid.
