Related to that would be to improve the existing error messages and warnings, in order to help the user pinpoint and fix the problem areas.<o:p></o:p></div><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;"><o:p> </o:p></div><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;">Recently I used modularize to help prepare some of the headers (mostly C, with some C++) from one of our platforms for modules, and that has given me a couple of ideas for places to start. These are mainly just general directions, and will need some digging into to figure what or if anything can be done:<o:p></o:p></div><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;"><o:p> </o:p></div><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;">1. I’m wondering if the messages like: ‘note: 'sigvec' at 378:8 not always provided” could be more helpful in providing the file name, and perhaps even the associated conditional directives that fire differently. Also, report it once.</div></div></div></blockquote><div><br></div>Yes, that would be super-useful.</div><div><br><blockquote type="cite"><div lang="EN-US" link="blue" vlink="purple" style="letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px;"><div class="WordSection1" style="page: WordSection1;"><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;">2.

Catch “extern “C”” problems. I had some problems where some “#include” directives were buried in some “extern “C” { }” blocks in some files and not in others. See if this could be detected.
