That's true.

A little bit? Did you read my other mail on the subject:

"That's an idea, but then we would be incompatible with upstream. I can
try to patch the configuration files of fpc so that it searches for
these binaries in /usr/x86_64-pc-fpc/sys-root/fpc/lib. But I prefer the
'standard' location. Also because other packages based in fpc relay on
that.

And what I've read here is that this path is chosen because mingw needs
a root filesystem location. Fpc does not need that, so I think I keep
the default locations, if that's ok."

The thing is that fpc does not need a complete build-environment or
something like that. It's just the compiler, one executable. Nothing
more. And offcourse the compiled object-files, we are discussing the
locations of these files only.

I think I can patch the compiler and it's configuration files. But I
think it's not really doable to patch Lazarus, a freepacal-ide, to use
these paths.

I can have a look.

Another thing, the MinGW packaging guidelines needs the packages to have
a 'MinGw' prefix, not suffix.

My example used a suffix, like 'fpc-win32'. Do you think I should use
'win32-fpc' instead? Again: this sounds logical when you have a complete
build-environment or something like that. But in this case I think
'fpc-win32' is more logical.
