Hi. My builds on my X86 solaris box have failed since yesterday, and I've just found bug 43615 in Bugzilla which indicates a different but similar issue for an x86-64 build.I'm running Solaris 10 on an older Dell box with a Pentium4 chip, and have been building gcc with the '--disable-multilib' argument for quite some time.
Here's the config info from the last build which worked: $ gcc -v Using built-in specs.

My builds on a sparc-sun-solaris2.10 from yesterday worked fine - on this machine GCC does _not_ use the '--disable-multilib' configuration switch. This mornings build has just started. My thanks to everyone working on GCC. Art Haas
