Re: Building gcc 4.6 without libiconv

[John Marino <gnugcc at marino dot st>]

For my part, I was able to build bootstrap compilers that pull in z, 
mpc, mpfr, gmp, and iconv statically.  That only left libc as a shared 
object, and that's acceptable for my use.  In case others are 
interested, the patch I used follows.  Maybe not the best, but it got 
the job done for me.
Thanks,
John
