bldprog-strtab-template.cpp.h@ 96550

Last change on this file since 96550 was 96550, checked in by vboxsync, 2 years ago
iprt/bldprog-strtab*.cpp.h: Increased the size dictionary to make use of character codes needed for string encoding as well as slot 0xff in ASCII mode (otherwise used for UTF-8 sequence escaping), however slot zero is not yet usable. Improved the compression a bit further by consindering one separator character following a word, thus using 'VERR_' instead of 'VERR'. The the iprt defines-only header claims a 53% compression rate, up from 38%. bugref:9726
