I haven't bothered adding specific symbols for different versions,  
since the symbols evaluate to six digit numeric constants anyway  
(where each pair of digits is a version number ... major,minor, and  
subminor).  So version 10.4 is 100400, 10.4.1 is 100401 etc

So if you write

#if OS_API_VERSION(100400, GS_API_LATEST)
// declarations here
#endif

All your declarations will be seen unless a programmer builds with  
GS_OPENSTEP_V set to a version earlier than 100400, and the generated  
documentation will tell you that your declarations are compatible  
with MacOS-X 10.4.0 onwards.

See http://www.gnustep.org/resources/documentation/Developer/Base/ 
Reference/index.html for more details.

Anyway, there is no problem adding more preprocessor constants rather  
than using the numeric values if you want ... we just put them in  
GSVersionMacros.h

I I guess we could use

#define GS_API_MACOSX_4_2       100402

or perhaps copy Apple with

#define MAC_OS_X_VERSION_10_4_2 100402
