Comment (by ryandesign):

 grisbi_osx.m is an Objective-C file (`.m` extension), not a C file (`.c`
 extension). To add flags for Objective-C files, the `OBJCFLAGS`
 environment variable is used, not the `CFLAGS` environment variable. The
 MacPorts option for that is `configure.objcflags` rather than
 `configure.cflags`.

 But if this is the only (or one of only a few) C89 incompatibilities you
 could instead fix them and [https://github.com/grisbi/grisbi/pulls submit
 them to the developers] or at least [https://www.grisbi.org/bugsreports/
 file a bug report about them]. Same for the type redefinition.
