I'd like to ping this request once again - it seems that there was no progress on this. The requirement actually is as follows: When building gcc on x86_64 (amd64), currently the resulting gcc (and g++, gfortran etc.) binaries are 64bit. This is unlike Solaris, where the binaries are 32bit. On both platforms, gcc is able to produce 32bit and 64bit binaries (thanks to the multilib support). For a network installation of gcc, with 32bit (i686) and 64bit (x86_64) Linux hosts it would be preferable, if the gcc binaries were 32bit - then gcc would run on both CPU types; and on the x86_64 systems, it would be able to build 64bit binaries with -m64. So far I have not found a way to pass -m32 selectively through the gcc bootstrap process such that the gcc (g++, gfortran, ...) binaries would be 32bit, while the multilib support would remain as is. Any hints are appreciated. Many thanks, Marek -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=22073
