My test was a program like this:
#include <stdio.h>
int main(int argc, char**argv)
{
int i;
for(i=0; i<argc; ++i)
printf("<%s>\n", argv[i]);
}
I built it under both Metrowerks and VC++. Then I called the program with
various command lines to infer the escaping rules. The two did not agree
on a few obscure cases, but both failed to parse the RcxCC exec line as
desired. In short, both treat
"foo\" abc
As a single argument that looks like this:
foo" abc
And not two arguments
foo\
abc
The differences between the two mainly have to do with weird cases like \\\\"
Assuming that VC++ is the defacto standard here, I think RcxCC should at
least quote in a way that VC++ would handle correctly. No escaping isn't
really an acceptable long-term solution, because even if I hack the
CodeWarrior libs to do this, people will still have problems if they use
VC++ to build NQC.

Nevertheless, I can only think that this whole escaping stuff is not compliant with normal, expected Win32 behavior. The backslash is the standard (...)
