These were defined backwards to the usual convention. #if GLSLANG_VERSION_GREATER_THAN(11, 10, 0) This reads as "if glslang version is greater than 11.10.0" to any reasonable sane programmer, and should therefore expand to "glslang_version > macro_argument". Yet the check it references was actually written as "macro_argument > glslang_version", thus expressing the completely opposite condition of "if glslang version is *less than* 11.10.0". This is definitely backwards and extremely, dangerously surprising behavior to any programmer familiar with such version macros. I'm not sure if anybody actually ever used them. I certainly didn't, on account of them being backwards. I could not find a single reference to them on GitHub (other than in copies of this header) - every project I found just used the GLSLANG_VERSION_MAJOR etc. macros directly.
