Summary: DBTS 501842: complete for 'cc' also on !GNU, !Linux and !Cygwin
Distribution: None
Originally reported in: Debian BTS
Milestone: None
Status: Fix Committed
Original bug number: 501842
Initial Comment:
* Completion for the various GCC compilers occurs on any system, but
only with a uname of GNU, Linux, or Cygwin will bash-completion add
those same completions to the "cc" command. bash-completion
probably assumes that other systems will not have gcc installed as
"cc".

Message:
If it would've slowed down load time, one could delay the action to the first time the completion is invoced. E.g. as is done for vncviewer:
_vncviewer_bootstrap()
{
local fname
case $(_realcommand vncviewer) in
*xvnc4viewer) fname=_xvnc4viewer ;;
*tightvncviewer) fname=_tightvncviewer ;;
*) fname=_known_hosts ;;
esac
# Install real completion for subsequent completions
complete -F $fname vncviewer
$fname # Generate completions once for now
unset -f _vncviewer_bootstrap
} &&
complete -F _vncviewer_bootstrap vncviewer

This is probably better, as this way we can ensure, that cc really points to the gcc. This is not likely to slow load time down.

Message:
The test whether to complete cc is now userland = GNU or uname = cygwin. Do we want to add something to the list?
We could do something like:
cc --version 2>/dev/null | grep -q GCC && complete -F _gcc cc
...but dunno if something like that is appropriate considering the test happens at completion load time (and would currently add some to the slowness of it).
