100: that they can be inspected during studying (and therefore JIT compiling). Note
101: that pcre_study() has its own set of options. Originally, all the options

108: Some options for pcre_compile() change its behaviour but do not affect the

114: variants:
115:
116: C1 Affects compile only
117: C2 Does not affect compile; affects exec, dfa_exec
118: C3 Affects compile, exec, dfa_exec
119: C4 Affects compile, exec, dfa_exec, study
120: C5 Affects compile, exec, study
121:
122: Options that can be set for pcre_exec() and/or pcre_dfa_exec() are flagged with
123: E and D, respectively. They take precedence over C3, C4, and C5 settings passed
124: from pcre_compile(). Those that are compatible with JIT execution are flagged
125: with J. */
