As I understand it the original design for glibc regex was that Emacs=20 was the default, so a flags value of zero meant Emacs. This is why=20 RE_SYNTAX_EMACS is 0. Evidently that design goal no longer holds, so it makes sense to adjust=20 Emacs's use of glibc flags to match the behavior of Emacs's only=20 regular-expression implementation in emacs/src/regex-emacs.c as best we c= an. However, surely this adjustment should be made in Gnulib, not in=20 etags.c. That is, gnulib/lib/regex.h (aka emacs/lib/regex.h) should=20 #define RE_SYNTAX_EMACS to equal RE_CHAR_CLASSES | RE_INTERVALS, not=20 zero. And eventually this change should be migrated back to glibc. I'll cc this to rms in case he has further comments about this.
