vim errorformat requires updating for gcc 4.5 unreleased

[Chris]

gcc 4.5 unreleased contains a column number for the "In file included from"
gcc 4.4 did not.
errorformat does not skip over the first line.
/opt/gcc-4.5/bin/g++ -std=c++0x -fshow-column c.cpp
In file included from a.h:3:0,
from c.cpp:2:
b.h:3:1: error: ‘dscfsdjvcsdfvsdf’ does not name a type
c.cpp:9:17: error: ISO C++ forbids declaration of ‘Params’ with no type
c.cpp:9:24: error: expected ‘,’ or ‘...’ before ‘&’ token
c.cpp: In function ‘int main()’:
c.cpp:16:2: error: ‘Params’ was not declared in this scope
c.cpp:16:9: error: expected ‘;’ before ‘p’
c.cpp:17:7: error: ‘p’ was not declared in this scope

Here are some lines I added to my errorformat to ignore:
In file included from... with and without column.

%-GIn\ file\ included\ from\ %f:%l:%c\\,
%-GIn\ file\ included\ from\ %f:%l\\,
%-Gfrom\ %f:%l\\,
%-Gfrom\ %f:%l:%c\\,

Please check if this patch works. I put the messages with :%c first,
I'm not sure if that makes any difference.

Hi, the patch does not work.
Some problems:
- The error contains a comma at the end (\\,) or a colon :
This can be done by adding
%*[\\,:]
- I don't know if it is necessary to use the "from" lines.

I tried a few things in errorformats, but I could not get the desired
effect. I don't know if it is possible.

A shell console for a simple include chain would give

/opt/gcc-4.5/bin/g++ main.cpp
In file included from b.h:1:0,
from c.h:1,
from main.cpp:1:
a.h:4:1: error: ‘csdcsd’ does not name a type
make: *** [all] Error 1

The vim error console window.
|| /opt/gcc-4.5/bin/g++ main.cpp
|| from c.h:1,
|| from main.cpp:1:
a.h|4 col 1| error: ‘csdcsd’ does not name a type
|| make: *** [all] Error 1

I guess the accurate thing to do would be ignore but display the "In
file included" and "from" lines.
