This question already has an answer here:
- Specifying size of enum type in C 9 answers
To ensure binary compatibility with the product I'm working on, I need to force some of my enums to be represented by a single byte.
Since C90 allows for the compiler to chose an appropriate type (6.7.2.2 Enumeration specifiers), I would like to force the compiler to chose 8 bits.
I did expect GCC attributes to allow this, but I could not find anything here. Is there another way to handle this? (or an attribute I missed)
I'm using GCC 4.6.4 for Microblaze and C90 (I did not see a relevant option here either).
