I can't explain this.  Cygwin/Window (interaction) problem ?

Good, config.log reveals:

--8<--
It was created by configure, which was
generated by GNU Autoconf 2.61.  Invocation command line was
--8<--

Ahem, gcc 4.1 really really needs Autoconf 2.59. This version, not
an earlier one, not a more recent one.

--8<--
configure:4310: arm-unknown-riscos-gcc -c -g -O2   conftest.c >&5
conftest.c:8:17: error: gmp.h: No such file or directory
conftest.c: In function 'main':
conftest.c:14: error: 'choke' undeclared (first use in this function)
conftest.c:14: error: (Each undeclared identifier is reported only once
conftest.c:14: error: for each function it appears in.)
conftest.c:14: error: expected ';' before 'me'
configure:4316: $? = 1
--8<--

This fails and configure concludes that there is no working cross-compiler
available.  However, the check on gmp.h is probably because of the newer
version of Autotools but I'm not 100% certain.
