I don't know how "standard" it is, but this is what I found:

The Microchip dsPIC30F math library has global symbols prepended
by one, two, and even three underscores.  

The "basic" math functions (48 in all) like add, subtract,
multiply, and divide for floats, doubles, and 32- and 64-bit
signed and unsigned integers all begin with three underscore
characters and are documented in the README.TXT file that came
with the library.

Another 45 functions covering trigonometric, hyperbolic,
logarithmic, exponential and other higher operations, all begin
with a single underscore character and are documented in
DS51456A, dsPIC Language Tools Libraries.

The library contains 54 additional functions whose names begin
with one, two, or three underscores, do not seem to be documented
anywhere, but which are nonetheless declared global.

It's kind of a mess.

I haven't found any such note, but I suppose I'll just have to
either avoid beginning any of my own symbol names with an
underscore or underscores, or else take special care to avoid
replicating any of the library names.

Thanks for the reply.
