I cannot replicate this bug with gcc-snapshot 20061022-1, the latest version available for i368. It seems that cstdlib is included by fixedComplex.cc: $ /usr/lib/gcc-snapshot/bin/cpp -fPIC -I/usr/include/octave-2.1.73 -I/usr/include/octave-2.1.73/octave -mieee-fp -O2 -Doctave_idx_type=int -DHAVE_OCTAVE_21 -DOCTAVE_FORGE -DHAVE_ND_ARRAYS -DTYPEID_HAS_CLASS -DCLASS_HAS_LOAD_SAVE -DMX_ND_RED_NUM=5 -DHAVE_OCTAVE_CONCAT -DHAVE_SWAP_BYTES -DHAVE_OCTAVE_UPLUS fixedComplex.cc | grep cstdlib | tail -n1 # 194 "/usr/lib/gcc-snapshot/lib/gcc/i486-linux-gnu/4.3.0/../../../../include/c++/4.3.0/cstdlib" 3 Could this be a problem specific to ia64 or gcc-snapshot 20070326-1? -- Rafael -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
