This is a bug report for perl from petercmartini@gmail.com
-----------------------------------------------------------------
Similar to RT 118623, Perl_cv_ckproto_len_flags is sensitive to spaces
when doing its checks for warnings.
For example,
perl -MScalar::Util=set_prototype -e 'BEGIN { set_prototype \&foo, "
\$ "; } sub foo($){}'
Prototype mismatch: sub main::foo ( $ ) vs ($) at -e line 1.
Which doesn't match the behavior if toke.c throws away the spaces:
perl -e 'sub foo( $ ); sub foo($){}' # No issues
Patch attached. The current ckproto is some code to produce the
warning inside of a 13 line if statement; instead of trying to nest
the cleanup in there, I broke those 13 lines into separate if () {
return; } blocks. If that's too much churn inside the function, I'll
redo it with fewer lines of code changed.
[Please do not change anything below this line]
