--- Comment #1 from Lance Bachmeier <lance@lancebachmeier.com> ---
This causes a similar problem with enums. I'm getting error messages like this:

#defines(1378): Error: variable `arma_example.FP_NAN` conflicts with enum
member `__anonymous.FP_NAN` at /usr/include/math.h(936)

The error message is confusing, because (a) I don't define FP_NAN in my program, and (b) the error message itself doesn't make sense, as arma_example.FP_NAN and __anonymous.FP_NAN are not the same thing.

Can you boil it down to a compilable example, please?

This new bug covers mine (not Adam's). It might be specific to including
math.h.

https://issues.dlang.org/show_bug.cgi?id=23622

A complete test case:

foo.c:

#include <math.h>

int main() {}

gcc foo.c -> compiles

dmd foo.c ->

#defines(797): Error: variable `foo.FP_NAN` conflicts with enum member
`__anonymous.FP_NAN` at /usr/include/math.h(855)
#defines(798): Error: variable `foo.FP_INFINITE` conflicts with enum member
`__anonymous.FP_INFINITE` at /usr/include/math.h(858)
#defines(799): Error: variable `foo.FP_ZERO` conflicts with enum member
`__anonymous.FP_ZERO` at /usr/include/math.h(861)
#defines(800): Error: variable `foo.FP_SUBNORMAL` conflicts with enum member
`__anonymous.FP_SUBNORMAL` at /usr/include/math.h(864)
#defines(801): Error: variable `foo.FP_NORMAL` conflicts with enum member
`__anonymous.FP_NORMAL` at /usr/include/math.h(867)

---- foo.c ------
#include <math.h>

int main() {}
---------

Now compiles without error. Though this has nothing to do with Adam's report.

Yes. My problem was fixed when you fixed this bug:

https://issues.dlang.org/show_bug.cgi?id=23622

I originally thought it was related to Adam's report, but that turned out to be wrong.
