local variable shadows parameter warning

Line 526 in 32b40e9

CharT ch_ = static_cast<CharT> (start_);

This local variable shadows function parameter >ch_<

CharT ch_ = static_cast (start_);

It is a trivial issue, but it is nice that somebody can rename this local variable.

Which compiler and warning flag? Spirit is not clear for -Wshadow.

I will check what I can do about it, however the last time I tried there were hard to fix local shadowing in macros and namespace global shadowing that requires an API breaking to fix.

hi,

First of all, thanks for your prompt response and I really appreciate your wonderful work to boost library which I sincerely hope to do a little bit of my part.

Compiler: gcc-10.2.0
warning flag: -Wshadow-compatible-local
boost: I tried 1.72 and see the latest one is the same as 1.72 on this particular issue.
example code: word_count_functor.cpp

I use the example code "word_count_functor.cpp" for testing (https://www.boost.org/doc/libs/1_72_0/libs/spirit/example/lex/word_count_functor.cpp)

Thank you again,

[nickhuang99]

BTW, just FYI, I am using this simple script to build/install my gcc-10.2.0 and hope it may save you some time if you haven't installed gcc-10.2 yet in your system.
