Re: can't build gcc-4.3 source since updating to 1.4.6

[Dean <dustaszewski@bulogics.com>]

I found the problem.  It wasn't in the build options as you mentioned. 
It was in the /etc/dpkg-config/cross-config.cache file.

line 158:
ac_cv_prog_cc_stdc=${ac_cv_prog_cc_stdc=-std=gnu99}

This seems to break the configure process, at least for gcc-4.3.  I 
simply commented it out and the build succeeded as it used to.  Of 
course I don't yet know what else will be effected by this change but it 
seems to be a bug.

Thanks
Dean
