WARNING: You will need re2c 0.13.4 or later if you want to regenerate PHP parsers, re2cregenerate

Host environment: CentOS6.5

PHP5.6.1

When compiling and installing PHP, an alert message is displayed: "configure: WARNING: You will need re2c 0.13.4 or later if you want to regenerate PHP parsers ."


Here it prompts an alarm instead of an error, but to verify whether it is fatal, you must understand the role of re2c
