I was asked if this was a known bug. It’s not. I don’t think anyone knows about it.
dvl: ping. FreshPorts truncates COMMENT. Known issue? https://www.freshports.org/devel/include-what-you-use/
Here’s what I found there:
Tool for use with clang to analyze
Here is what the Makefile contains:
$ grep COMMENT Makefile COMMENT= Tool for use with clang to analyze #includes in C and C++ source files
Here is what the command returns:
$ make -V COMMENT Tool for use with clang to analyze
It appears the line is treated as containing a comment.
