| | | | | | | themselves, with the proper quotes added. Matches gnu-m4, not Solaris nor FreeBSD... better for robustness, as it makes for more transparent expansions.
* Recursive definitions are not the real problem.espie1999-12-211-7/+10
| | | | | | | | | | | | | Trying to expand them is. So flag obvious recursive definitions for later, and give an error only if we expand them. (Some gnu-m4 files, including autoconf, do define some macros with themselves as the replacement text, for use in test-if-set patterns) Since type is no longer MACRTYPE, those macros end up in builtins... but this is not a problem, since expanding them is an error.
* Clean up comment/quote recognition a little bit:espie1999-11-301-6/+6
| | | | | | | - use strlcpy to make clear that the strings are line terminated, - remove the number of magic constants, - use assert() for preconditions, - use puts instead of looping over array of chars...

| | | | | | Let indx match netbsd flavor, to simplify diffs. Show how many quotes were not closed. Increase stack slightly, now that we're no longer bound by argspace.

| | | | | Simply put, mkstemp/unlink/rewind has the proper semantics under Unix, and so we don't have to keep track about temp file names and remove them.
