KOffice workaround for raspbian-wheezy

Hi all, from the very beginning, when they were included builds for raspbian-wheezy, I watching FTBFS in KOffice with reference to a compiler bug. See: /build/buildd/koffice-trinity-14.0.0-r313/./chalk/core/kis_exif_value.cc: In member function 'TQString ExifValue::toString(uint)': /build/buildd/koffice-trinity-14.0.0-r313/./chalk/core/kis_exif_value.cc:685:1: error: unrecognizable insn: (insn 676 675 677 19 (set (subreg:SI (reg:DI 378 [ D.20205_111->m_sbyte ]) 0) (sign_extend:SI (mem/s:QI (plus:SI (mult:SI (reg/v:SI 269 [ i ]) (const_int 8 [0x8])) (reg/f:SI 374 [ this_1(D)->m_value ])) [0 D.20205_111->m_sbyte+0 S1 A64]))) /usr/share/tqt3/include/ntqstring.h:949 -1 (nil)) /build/buildd/koffice-trinity-14.0.0-r313/./chalk/core/kis_exif_value.cc:685:1: internal compiler error: in extract_insn, at recog.c:2109 Please submit a full bug report, with preprocessed source if appropriate. See <file:///usr/share/doc/gcc-4.6/README.Bugs> for instructions. Because in the last days Michele worked on fix build KOffice with Ruby 2.1 and libwpd-0.10 (good work Michele!), I devoted some time to explore the problem on Raspbian. I've isolated the problem and then created a workaround. Please see the attached patch. What is your opinion? Can I push it? Thanks, -- Slávek
