[Vala] Vala and side by side execution

[Carl <name is carl gmail com>]

Hello,

I'm working on releasing vala 0.13.3 (plus other improvements :) for Windows
and I'm facing an issue with side by side execution.

I have to test many flavors of minor releases (0.13.1, 0.13.2, 0.13.3) and
all have the vapi files installed in the vala-0.14 folder of a user
directory (well for Windows it's C:\Documents and Settings\All
Users\Application Data\vala-0.14).

The folder being named after the major version (and not the complete version
ie 0.13.3) , the vapis get overwritten each time I install a new release of
Vala.
To the point I'm no sure which vapi files I run :)
So I can't have 0.13.1 and 0.13.3 running by side by side because the two
releases share the same vapi files.

Am I the only one experiencing this ?

Regarding this matter, I have two questions :

1) Are the vapi meant to be located in a user related folder ? They didn't
strike me as being configuration, nor personal to the user. Am I missing
something ?

2) Couldn't we enable side by side execution for minor releases (for
example, by naming the vapi folder "vala-0.13.3" instead of "vala-0-14", or
by having it in the application folder, not shared in the user folder) ?
What do you think about it ?

Cheers,
Carl
