What you normally do is keep away from reflective surfaces as far as possible and then remove the part of the impulse response after the first reflection thus you end up with a 'quasi-anechoic' response. The trade off is in the frequency resolution, increasing the distance from reflective surfaces will increase the resolution and simultaneously decrease lowest measurable frequency.
See this post on
Tweeter Measurements for details on the importance of a proper microphone mount. Notice that the legend below the diagrams tells you the parameters of the measurement, most importantly the FreqLO which is the resolution and lowest measurement frequency.
