[xsd-users] Linker error with double types when using wchar_t

[Macumber, Daniel]

I am having trouble with double types when using xsd cxx-tree with --char-type wchar_t in xsd 3.2.  Specifically, the linker seems to be looking for and missing methods returning special characters related to nan, infinity, etc that have to do with doubles.  I have modified the hello.xsd and driver.cxx files as shown below to add an optional double element ("number") to the schema and support the wchar_t character type.  I have seen related issues on this list before but none specifically mentioning the problem with double types.

Thanks a lot,
Dan
