Error when compiling the source codes to produce the documentation

[SwitWu]

I want to compile source codes and get the documentation with a larger font size for self-use. An error occurs but I could not find where the problem is.

I think the main file is unicode-math.ltx and I run it with xelatex.

Thanks for this — this is because of a new conflict between the amsmath and refstyle packages. If refstyle is loaded first it will fix the problem (already fixed in the source).
