Compiler dies (segfaults!) while building the text editor test program. I turned off '.SILENT' so that the compiler flags can be seen. All errors included (including "remarks")

editor.cxx in the test phase contains a lot of UTF-8 characters inside a text string. It seems that the compiler does not know how to deal with 8 bit characters. Just remove the text from editor.cxx and you will be fine. It will go anyway as soon as I get confirmation that Fl_TExt_* stuff runs.

Wow, yep -- that was it.

IMPORTANT NOTE: I found I couldn't just #ifdef away the utf8 text..
it still crashed even when it was #ifdef'ed out.
I had to actually /delete/ the utf8 code from editor.cxx
to prevent the crashes.

Apparently it's the C pre-processor was crashing (or some
intermediate phase thereof), and not the compiler itself.

Maybe there's a flag for '--dont-segfault-on-nonascii-strings' ;)

I'll leave this open until the official release builds OK
(ie. when the UTF8 text is removed).
