So you're asking for a manpage, really.

Yes, either that or using whatever variable cygport sets up with the correct objdump. > What this line is doing is obvious, the rest of this block, not so much.

I was using this to figure out why the "objdump -d -l" was missing some of the file names I was seeing (in general, again, it comes to the same set of files in the end). > If you're going to keep this (which you probably should), perhaps it > should be under some 'if (DEBUG)' conditional. Yeah, can do if I use GetOpt::Long, which I should probably do anyway just in case this gets extended later on. > DWARF_PARSE should be mentioned in the documentation for cygport.conf Yes. > Since the helper script will be installed, it could be made a boolean. Out of habit grown over decades, I always keep an escape hatch for using local (modified) copies in such scripts.
