Thanks, that got me much further. I am currently finding out
what other 
bits and pieces I need to eliminate by a process of trial
and error - 
there sure are a lot of options. I've also now disabled a
couple of 
other options, and discovered I need --without-regex. The
current 
configure is

$ ../configure --prefix=/home/wx28/
--enable-rpath=/home/wx28 
--disable-stl --disable-std_string --disable-log
--without-regex

and I am currently failing to compile string.cpp:

../src/common/string.cpp: In member function `bool 
wxString::ToULong(long unsigned int*, int) const':
../src/common/string.cpp:1722: error: `wcstoul' undeclared
(first use 
this function)
../src/common/string.cpp: In member function `bool 
wxString::ToDouble(double*) const':
../src/common/string.cpp:1759: error: `wcstod' undeclared
(first use 
this function)
make: *** [basedll_string.o] Error 1

I presume that the required definitions are being omitted
conditionally? 
I wish I'd recorded the options I used to configure the
first time through.

Oh well, I'll get there in the end - though after I manage
to build for 
Cygwin the packaging requirements look a little daunting if
we want to 
mae it a standard component.

Thanks again for your help, and good luck with the blog: it
looks very nice!

regards
  Steve
