Hello,
The following C source code is not highlighted properly.
Lines between #if 0 and #endif is not highlighted as comments.
if(
#if 0
cond0 &&

but if I remove the "if(" they are highlighted as comments.
Hmm. I can't quickly think of any reason not to allow this.
The diff below contains the fix.
To make the change manually, start up vim and
:e $VIMRUNTIME/syntax/c.vim
/syn cluster\tcParenGroup
:s/cCppOut,//
:!mkdir -p ~/.vim/syntax
:sav ~/.vim/syntax/c.vim
:q
The :!mkdir and :sav lines will need to be slightly different if you are on
Windows. For starters, .vim will be vimfiles. Hopefully you can figure it out.
Anyway, this will put a revised c.vim in your ~/.vim/syntax directory, which will
override the one distributed with Vim. So it won't benefit from updates to the Vim
C highlighting that come through, but also won't have the bugfix undone for the
same reason. If/when the bugfix is incorporated into the c.vim distributed with
Vim, you can remove the file from ~/.vim/syntax to use the Vim one again.
Ben.
