Ada build now requires gnatmake?

[Richard Kenner]

    I just did an update and tried a bootstrap, and it seems that gnatmake
    is used to build the Ada compiler, specifically to build treeprs.ads,
    einfo.h, sinfo.h, and nmake.adb.  I thought bootstrapping was only
    supposed to require the compiler and gnatbind.

Those files are in the tree, but you may have to do a "touch" if they are older
than what they depend on.
