I used gcc 4.0.2 as the bootstrap compiler. I believe that the error doesn't occur when gcc-3.4.4 is used.
Is this issue still present ? If the issue is with the bootstrap compiler, there's not much we can do. Arno

This doesn't occur on linux, but it doesn't need the -mdisable-indexing hack. I'll try to investigate further. Dave

The error doesn't occur with 3.4.4. I have a build of 4.1.0 underway. If the build is successful, I will install and test it to see if the miscompilation is still present with 4.1. There was a recent fix that should make debugging easier. Is GNAT still being maintained in the 4.0 branch? Dave
Subject: Re: make[2]: *** [ada/einfo.h] Error 1 > Is GNAT still being maintained in the 4.0 branch? Yes, although only critical changes go there (as you would expect for a release branch). Arno
Still fails as of 2006-02-05 with 4.0.2 bootstrap. Not present in 4.1.0 20060127 (prerelease).
Given that 4.1.0 has been released and issue is fixed there, closing this PR. Arno
