--- Comment #5 from Walter Bright <bugzilla at digitalmars.com> ---
importc.h has the following lines in it:

    #undef __has_extension
    #define __has_extension(x) 0

so:

    #if __has_extension(gnu_asm)

should become:

    #if 0

I don't know what is going wrong here. Maybe __has_extension cannot be
undefined?
