Use via Inline::C with compiler flags is broken #430
Description
An Alien that sets cflags to something like -Ifoo -Dbar breaks when used via use Inline with.
The reason is that Alien::Base’s Inline() method puts all these flags into INC, while Inline::C quotes spaces in INC when flags other than -I appear inside it. The INC value that Inline::C passes on to EU:MM becomes "-Ifoo -Dbar". Consequently the compiler doesn’t look for a directory named foo, it looks for a directory named foo -Dbar instead.
A somewhat hacky workaround might be to include at least one double quote in cflags, which would currently prevent Inline::C from adding further quotes in its quote_spaces() function.
But I think the proper solution for Alien::Base would rather be to revert #109, putting the -D and other flags into CCFLAGSEX instead.

Yeah my preference would be to revert #109. However I think we may need to try to fix
ExtUtils::Dependsor maybe just return the broken config whenExtUtils::Dependscalls the ABInlinemethod.plicease commentedon Sep 21, 2026
I've deployed #443 as a dev version
2.89_01. Can you give it a try? Either way will probably do a prod release with this change in the next couple weeks or so.johannessen commentedon Sep 23, 2026
Frankly I am not interested in “giving LLM output a try.”

okay then.
