Is it a word or an acronym? Or neither?
Although: "Since C++ is integral to gcc, djgpp no longer stands for "DJ's G++" but probably stands for something like "DJ's GNU Programming Platform"." [2]
"Couldn't we rework that command to not use + separators?"
"No, far better to take that character out of consideration."
Unix: "Filenames can use control characters. I don't care if that makes pipes between commands really complicated! Add an option for NUL-separated filenames if you have to."
copy /b file1+file2 outputor would you start another jif/gif-kinda war over this with the author? XD
Also I can see that Paul Graham's "my website my rules" is even stronger than mine or DJ Delorie's, so Djgpp is also correct (if not by the Gods, then by fist).
That strongly reminds me of "it's spelt Raymond Luxury-Yacht, but it's pronounced 'Throatwobbler Mangrove'".
Additionally, word-initial single G before short I is always [g] instead of [dʒ] in native English: gift girl give gibbon gimlet gizzard gilded git gimp giddy gig gimbal.
The exceptions are borrowed French words: gin (le gin), ginger (le gingembre), giraffe (la girafe), giblet (OF: gibelet).
