bug#24069: gcc man page is broken

[Danny Milosavljevic]

$ man gcc

 Manual page gcc(1) line 1/2 (END) (press h for help or q to quit)

$ ls -l /home/dannym/.guix-profile/share/man/man1/gcc.1.gz

Err what?

That's also the case for the normal gcc package (for example 4.9.3).

But

$ info gcc

works fine.

bug#24066: icecat "mailto" handler does not work - and cannot be reconfigured by user

Whoops. I should have read the page better.

However, clicking on that button in icecat does not send E-Mail for me. 

Monitoring the network interface I can see that it redirects to a mailto: URL. 
So that's nice.

Checking the application preferences of icecat, it only gives "always ask" 
(note: it doesn't ask) and not an application for "mailto". (in GuixSD)

Creating my own HTML page with a mailto link doesn't work either.

Therefore, I reported a bug to Guix too.

Bug report follows:

"mailto:; links don't work in icecat.

Checking the icecat source code, there are several ways to handle E-Mail. One 
of them is as "external helper app". One of those (not sure whether it's the 
correct one) uses gio's g_app_info_launch_default_for_uri in order to launch 
helper applications.

There is a test 
icecat-38.8.0/uriloader/exthandler/tests/unit/test_handlerService.js that does:

  let isLinux = ("@mozilla.org/gio-service;1" in Components.classes);
  if (isLinux) {
// Check mailto handler from GIO
// If there isn't one, then we have no mailto handler
let gIOSvc = Cc["@mozilla.org/gio-service;1"].
 createInstance(Ci.nsIGIOService);
try {
  gIOSvc.getAppForURIScheme("mailto");
  noMailto = false;
} catch (ex) {
  noMailto = true;
}
  }

And this ./toolkit/system/gnome/nsGIOService.cpp uses 
g_app_info_launch_default_for_uri .

Therefore, I tried it out:

#include 
#include 
#include 

int main() {
GError* error;
g_app_info_launch_default_for_uri("mailto:f...@example.com;, NULL, 
);
// g_app_info_launch_default_for_uri("http://www.google.at/;, NULL, 
);
if (error) {
g_warning("err %s", error->message);
g_error_free(error);
return 1;
} else
return 0;
}

I get:

** (process:12464): WARNING **: err Operation not supported

If I debug it some more I get:

$ strace -f ./g 2>&1 |grep open |grep -v ENOENT
