--- Comment #1 from H.Merijn Brand <h.m.brand at xs4all dot nl> 2011-07-14 11:09:18 UTC --- FYI I completed building gcc-4.6.1 with gcc (GCC) 4.2.4 GNU assembler (GNU Binutils) 2.18 gmp-5.0.2 mpfr-3.0.1 mpc-0.8.2 on HP-UX 11.23-ia64 and HP-UX 11.31-ia64 (both IPF/Itanium 2) without too much trouble using the generated gcc to build perl from scratch worked out fine for both 32bit (-milp32) and 64bit (-mlp64) configurations. The gcc builds are now available on my site http://mirrors.develooper.com/hpux/gcc.html
