As you noticed the issue has been fixed, thanks for your cooperation.
The issue has been the use of an assembler instruction that is not
supported on Windows CE.

Windows CE only supports the armv4 instruction set, and currently the
default for code generation seems to be armv4 or less, so this works at
the moment. I'm not saying that this default choice will change in the
future, just to avoid unnecessary complications if it does.

So when compiling the crosscompiler/RTL for Windows CE, consider
specifying -Cparmv4 in CROSSOPT to avoid issues with unsuitable code
