trouble with compiling using arm gcc 7

[simvv-exe]

Hi!
I really interested in this library, and I want to use it in my project for embedded systems.
Unfortunately it doesn't compile using arm-none-eabi-gcc 7.2.1.
Here's a link.

Thanks in advance.

Hi @RB37,

I am glad you like this library. I will take a look at this and try to make it compile ASAP.
Will keep you informed about the status.

Thanks

It compiles just fine for me. Take a look at it https://godbolt.org/z/8nG83j.
Maybe you are not using the latest version.

It does not compile if you don't include iostream first

Update:
I figure it out. Its just a missing header. Everything work fine if before including bitflags I include < utility >.
It probably should be included inside a library.

You are right. utility header is needed. If you would like to contribute, you may add it.
