Where? Can you please explain why this is needed? What error message
did you encounter that prompted the change?

c++ -c -I. -I.. -I../liboctave -I../src -I../libcruft/misc -I../glob -I../glob -DHAVE_CONFIG_H -fno-implicit-templates -g -O2 -Wall -o toplev.o In function `class octave_value_list Foctave_config_info(const octave_value_list &, int)': parse error before `:' parse error before `:'


from oct-conf.h

Its the -DSEPCHAR_STR=":" that needs to be changed to -DSEPCHAR_STR=\":\"
Apparently the same fix is needed for MachTen according to the README.MachTen file.

Did you search .o files? They are mangled symbol names. You'll
probably need to use something like

for f in *.o ; do echo $f ; nm $f | grep get_size__Ct6Array21Zcii ; done

to find them.

I searched the *.o files with nm -o and couldn't find the missing symbols. e.g.:

[:~/Develop/octave/liboctave] % nm -arch all -o *.o | grep get_size__Ct6Array21Zcii
Array-ch.o:00006640 S __Q2t6Array21Zc26get_size__Ct6Array21Zcii.0.MALLOC_OVERHEAD
Array-ch.o:00000004 C
Array-ch.o:00000008 C __Q2t6Array21Zc26get_size__Ct6Array21Zcii.2.dl
Array-ch.o:00000004 C __Q2t6Array21Zc26get_size__Ct6Array21Zcii.3.max_items
Array-ch.o:000014bc S _get_size__Ct6Array21Zcii
MArray-ch.o: U _get_size__Ct6Array21Zcii
chMatrix.o: U _get_size__Ct6Array21Zcii

I could be missing something here. I've only used the gcc/Unix combo the last couple of months...
