    Did you actually try doing this?  Do you have a simple example
    that fails?  If so, please show it.

Here is the macro:

@macro gradesymbol {}
@iftex
@math{\\circ}
@end iftex
@ifnottex
°
@end ifnottex
@end macro

Which I'm trying to use like this:

   It's optimum if you can keep the inside temperature of the chamber
   at around 21 @gradesymbol{}C (70 @gradesymbol{}F)

But the result is rendered with an extra space between the grade
symbol end the following letter C (or F) both in TeX (DVI) and Info
formats:

   It's optimum if you can keep the inside temperature of the chamber
   at around 21 ° C (70 ° F)

This unwanted space does not appear when I write the macro without the
conditionals (which makes the degree symbol visible only in the TeX
format, of course):

@macro gradesymbol {}
@math{\\circ}
@end macro

The full example document follows:
