I Think I have access to a 6.5.4 box too... but am not sure. That would be fine, in case I get around to investigating this further. On many other platforms (like Tru64 UNIX), it used to be possible to fix or work around problems like this, provided the number of different cases/releases don't get out of hand. Before I start this, I'll probably have to invest some work to get mainline to fully bootstrap on 6.5.2x, though. SGI says that binaries compiled on different minor releases should be compatible each other, I wonder if a binary packager can safely build on = 6.5.18 and expect it to work on older boxes too or not... Certainly not: this only works the other way round: you can build on 6.5.x and run on 6.5.y, y x. There are new symbols introduced e.g. in libc, which are marked as OPTIONAL in nm output. It is possible (though I don't remember how this is done) to check for those functions as runtime and use them only if available. This is certainly far too much trouble in the GCC case, though.

I have no mips-sgi machines available and if the port maintainers are not going to help help likely we will not make progress. In any case, this is not a regression, because 4.1.0 bootstrapped but only with all the wchar_t facilites disabled: you can obtain the same behavior now passing --disable-wchar_t to configure. In case you want to help, I suggest first trying to figure out the differences between your machine and this one, which works fine: http://gcc.gnu.org/ml/gcc-testresults/2006-07/msg00360.html I'm sure Eric is available for that. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=27878

--- Comment #14 from pcarlini at suse dot de 2006-06-12 22:40 --- Ok, thanks for your feedback. Indeed, the only possible cause of the problem are the finer grained checks for wchar_t vs C99 wchar_t proper functions which are now carried out after my 2006-05-03 commit (which fixed regressions on solaris and hpux). In fact, looking at the 20060428 log what was happening before the patch is that ac_c99_wchar was no and then wchar_t ended up being *completely disabled*. Currently, instead, the autoconf tests try to enable wchar_t support (all the configure tests pass) but then something very misteriously fails at build time. All in all, waiting for someone to kick-in and shed some light about MIPS vs MIPS64 and all that, you can certainly force by hand the old (4.1.0) behavior by passing explicitely --disable-wchar_t at build time. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=27878

I do not understand: the configure tests apparently are enabling wchar_t
support. Can you double check that you can indeed compile (with 4.1.0, for
example) this C++ snippet:

}
