Some ideas.

Answer to Flo : of course single words should not be translated as
_("segmentation")+_("fault"). But there are cases where you have to trans=
late single
words, like for the title of a column in a table : _("host"). But in that=
 case, it's the
translation of a sentence that contains one word, so it's the same : tran=
slate as much
as possible in one string :)

About destructive/non-destructive methods for translations : never be afr=
aid of breaking
a translation. The software is first designed to work, and then to work i=
n foreign
languages, and not the other way round. A recent example : sylpheed (a ni=
ce mail client)
was released as 1.0. This usually means stable and tested version, and yo=
u don't expect
for a newer version before a while. Few weeks after, 1.0.1 was released. =
Changelog :
many translations updated.

Now, Alex's subject : this is NOT a translation problem. It is a keyword =
problem.
So you have to put #ifdef USE_NAGIOS and #ifdef USE_ASNMTAP everywhere.
When it's only a keyword problem, here is what you can do :
#if defined ENABLE_ASNMTAP
#define APPLICATION_TITLE        "ASNMTAP"
#endif
#elsif defined ENABLE_NAGIOS
#define APPLICATION_TITLE        "Nagios"
#endif

Then, in the application, you can use this :
char*application =3D strdup(_(APPLICATION_TITLE));

Here you see that you define the keywords to use somewhere, and you enabl=
e the
translation system (as _(...) ) somewhere else.

I wrote an incorrect example to make things clear about keywords and tran=
slation. It's
incorrect because if you write this, the i18n tools will not see that "AS=
NMTAP" and
"Nagios" are strings to translate. The correct example is :

#if defined ENABLE_ASNMTAP
#define APPLICATION_TITLE        N_("ASNMTAP")
#endif
#elsif defined ENABLE_NAGIOS
#define APPLICATION_TITLE        N_("Nagios")
#endif

Then, in the application, you can use this :
char*application =3D strdup(_(APPLICATION_TITLE));


N_(...) does nothing but tell the translation system that it contains a s=
tring to
translate. The translation occurs only when you use _(...).

I suggest that you make a variable, not a #define constant.
This way, you can enable/disable asnmtap at runtime, and have one binary =
only.

This creates a problem for the CGI because it should read one config file=
 for nagios
behaviour and another file for asnmtap behaviour. I suggest that you use =
an environment
variable (no problem to use it for perfparsed and perfparse tools too) to=
 say where the
config file is.
There would be 3 ways to say where it is, and the priority would be
1/ check if -c is set and take the config file name from the command line
2/ if -c is not set, check if PERFPARSE_CONFIG_FILE is set and take the c=
onfig file name
from that environment variable
3/ otherwise, use the default built-in config file name.
In all cases, if the config file does not exist, use the built-in default=
 values.

With this, you can edit your httpd.conf file and add the environment var =
:

<directory /your/web/repository/nagios/cgi-bin>
  Options ExecCgi
  ...
  SetEnv PERFPARSE_CONFIG_FILE /perfparse/etc/perfparse.conf
</directory>

<directory /your/web/repository/asnmtap/cgi-bin>
  Options ExecCgi
  ...
  SetEnv PERFPARSE_CONFIG_FILE /perfparse/etc/asnmtap.conf
</directory>


Then, no need to hard-code the paths at ./configure time. Just have 2 dis=
tinct
configuration files :)
