I have the manual for 2.59.
It contains the paragraph:
The option's argument is available to the shell commands
ACTION-IF-GIVEN in the shell variable `enableval', which is
actually just the value of the shell variable `enable_FEATURE',
with any `-' characters changed into `_'. You may use that
variable instead, if you wish. The HELP-STRING argument is like
that of `AC_ARG_WITH' (*note External Software::).
It is ambiguous whether the phrase "with any `-' characters changed into
`_'" refers to the FEATURE name, and hence the variable name (which appears
to be the case) or its value.
I suggest changing the text starting "shell variable" to:
"shell variable named `enable_FEATURE', with any `-' characters in FEATURE
changed into `_'."
