Parser does not like multiline `#if` conditions

IDE: Visual Studio X/Fire
Version: 10.0.0.2457 (develop)
Target (If relevant): Island(OSX)
Description:
I found this #if condition, and Elements doesn’t like it.

Expected Behavior:
Compiles fine.
Actual Behavior:
See below.
Steps:

#if arch(i386) || arch(arm) || arch(powerpc64) || arch(powerpc64le) || arch( // E271 identifier expected, got 
s390x) // E1 #endif expected, got )
	   // E477 Declaration expected
	   // E46 Unknown identifier "s390x"

#endif
