It seems that nobody really noticed adding -l switch to .h
creation rule.
Good :)
Still, currently the rule system makes everything recompile
even if I only touch .mx file containing .h.
The reason is, .h rule doesn't contain -n switch (don't
touch unchanged files) for Mx.
I suggest adding -n to .h and possibly also other rules (.c
.y and so on).

We should not confuse matters. The original request is to
remove #line directives from Mapi.h. More generally,
removing them from all .h files should be no problem. Since
there is (or certainly: should) not be any executable code
in .h files, #line directives don't do anything for the
debugger.
As to comments in Mapi.h, definitely! The whole Mapi.mx
documentation should be redone.

The #line statements are needed to keep track of the
location when you are running with a debugger/profiler.
Droppping #line could mean there is not enough documentation.
In the rare cases #line was a stand in the way I took the c-file
and deleted the lines with a simple edit command

Just no to forget this:
Both, Martin and Marcin are right (which is not too
supprisingly, since there names differ by only one character
... ;-):
Yes, #line statments are needed for debugging as long as the
originaly .mx file is still available, i.e., during "make"
in the build directory.
After "make install" (or "make rpm") however, the .mx file
is gone, and then the #line statements are actually "wrong"
and "hinder" convenient debugging.
Hence, the core of this feature request boils down to
- remove #line statements from header files during "make
install"
- make sure that there is (some) documentation left in .h
files after they got extracted from a .mx file.
[Quite busy here for a low-priority feature request ... ;-)]

I only want #line removed from .h files provided for external users, e.g.
Mapi.h.
I'm pretty sure one day there will be a need for separate distribution of
libMapi and libMapi-dev (e.g. to compile MonetDB PHP client ;)), and then
it
would be handy.
It's not urgent though :)

Indeed, -l would be just enough, but I don't how to add the switch only
for
creation of this file.
