Hi Bruno,

Thanks for the report!

So the problem is (log3):

which shows that the scanner was compiled before the parser was
generated, and since the scanner uses parse.h, it fails.

I expect the appended patch to fix your issue.  Could you
please give it a try?  A tarball with it is available here:

    build: make sure parse.h is generated before using it
    
    "make check" fails with Solaris' make, because it compiles the scanner
    before parse.h is generated.

    We need parse.h.

    (BUILT_SOURCES): Remove.
