gnatmake vs gprbuild (win32, GPL 2014 and 2015)

gnatmake vs gprbuild (win32, GPL 2014 and 2015)

[gautier_niouzes]

Hello,

On the same project file, I get a different behaviour at the link phase.

  - gnatmake succeeds [1]
  - gprbuild fails [2]

Since gprbuild is meant to replace gnatmake over time, I'd like to have a successful linking with gprbuild. Detailed error messages below.

So my question is: with which linker option can I fix that ?

The problem shows up on both GNAT GPL 2014 and 2015 versions.
TIA

Obviously, gnatmake (GPL 2016 vintage) tries now with gprbuild first (you see "gprbind" appearing at some point in the messages), then, if the build fails, tries again with its "traditional" way (gnatbind, gnatlink).
Did someone notice it as well ?
