Hi Jay,
true, but:
#define
rw_sv_def(q, _txt) { const char * qu = #q; \
if (!strncmp(qu, "Quad_", 5)) { UCS_string ustr(qu +
5); \
if (ustr.starts_iwith(qxx))
matches.push_back(ustr); } }
So before adding 5 I check that the string starts with "Quad_"
, (and if so then it is long enough).

Hi Jürgen,
It's warning about line 51:
rw_sv_def(CHI, "{ ... } axis argument")
In this case you get "CHI" + 5, which is indexing way off the end of
the string, which is why it's warning.

Hi,
I believe by string they mean a simple string literal. What I am doing is.
for example
"Quad_CT" + 5 (and so on for many ⎕xx functions and variables).
The "Quad_CT" string literal, is, of course, not spelled directly (because
then I could have
used "CT" instead) but by macro expansion of #Quad_CT. That is, #Quad_CT is
stringified to
to "Quad_CT" which is then offset by 5 to get "CT".
Peter's compiler seems to be a little picky at times.

I think the problem here is that std::string doesn't have an overloaded
operator that takes an int. Thus, what happens is that the string gets
coerced into a char *, which is then offset using the integer.
Thus, if that's what you want you should make it clear using
(someString.c_str() + offset). Or if you want to keep an std::string, then
someString.substr(offset) should be used.

Hi Peter,
I believe I managed to fix the sem_xxx warnings in SVN 625.
The Postgres warning should remain because it points at a harmless but
somewhat incomplete
SQL installation.
The final warning seems to make no sense at all. And yes, adding an int to
a string does not append
to the string but skips the beginning. That was the plan.
