Hi Daniel,
the two issues are the following:
1. CPP includes a C header where there is some m4 code to expand, and *m4*
finds an error. Then m4 typically will not report its error message using the C
header name.
2. m4 expands a multi-line macro, then the resulting C code contains an error.
Then gcc will become confused about line numbers.
At least those were the issues when I was working on this. Maybe they have been
fixed since?
Best regards,
