Hi all,
Is there anyway to get the Info.plist preprocessor NOT to add whitespace between tokens during macro expansion?

This works. The two-stage construction does the trick.
Robert


#define VERSION_MAJOR 4
#define VERSION_MINOR 0
#define VERSION_BUGFIX 0

/* Symbols needed for Info.plist; ugly multistage construction because
  they need to be symbols, not strings, no quotes, no whitespace */
#define MACRO_PASTE_5(a, b, c, d, e) a##b##c##d##e
#define MACRO_PASTE_5A(a, b, c, d, e) MACRO_PASTE_5(a, b, c, d, e)
#define MAC_CFBUNDLE_SHORT_VERSION_STRING \
  MACRO_PASTE_5A(VERSION_MAJOR, ., VERSION_MINOR, ., VERSION_BUGFIX)

The symbol MAC_CFBUNDLE_SHORT_VERSION_STRING now gives the desired result and can be used in your Info.plist.
