I'd prefer inline functions such as:

static inline GLboolean
_mesa_is_desktop_gl(const struct gl_context *ctx)
{
    return ctx->API == API_OPENGL || ctx->API == API_OPENGL_CORE;
}

static inline GLboolean
_mesa_is_gles(const struct gl_context *ctx)
{
    return ctx->API == API_OPENGLES || ctx->API == API_OPENGLES2;
}
