Yes, that's what I need.

export CFLAGS="-O2 -pipe -march=pentium-m -mtune=pentium-m -m32"
export CXXFLAGS="${CFLAGS}"

I use CFLAGS based on this article:

https://wiki.gentoo.org/wiki/GCC_optimization

Is that info irrelevant to Claws Mail?

Hm. I have never used --host on any machine so far. I
don't even know what it does. Is it mandatory?

Also why in your example --host is 32-bit and --build
is 64-bit? Shouldn't they be the same bit depth?

I can check that but I can't find a list of
dependencies in the docs (although I obviously have
all satisfied on the current 64-bit machine). Where
should I read please?
