This week I had another look at this.
To cross-compile on Windows I first install Cygwin. Then I use a MinGW build
script to compile the latest GCC using Cygwin's compilers. And it's this latest
GCC binary I'm using to compile everything that follows, including the latest
NASM.
It suddenly occurred to me that in order for NASM to read Cygwin paths I had to
compile NASM with Cygwin's GCC rather than MinGW's GCC.
And after having done so my hunch proved to be correct and FFmpeg's 'configure'
was happy again:
nasm -v
