Vim 7.4.465 does not compile on AIX 6.1

[GoogleCodeExporter]

What steps will reproduce the problem?

1. Create make file
   ./configure --with-features=huge --enable-gui=no
2.
   Execute make command

It compile, and stop with two error, the text output for the first error, 
commented line error:
--->    mkdir objects
        CC="cc -qlanglvl=extc89 -Iproto -DHAVE_CONFIG_H        " srcdir=. sh ./osdef.sh
        cc -qlanglvl=extc89 -c -I. -Iproto -DHAVE_CONFIG_H     -g       -o objects/buffer.o buffer.c
        cc -qlanglvl=extc89 -c -I. -Iproto -DHAVE_CONFIG_H     -g       -o objects/blowfish.o blowfish.c

"regexp_nfa.c", line 4410.1: 1506-046 (S) Syntax error.
make: The error code from the last command is 1.

  I modified the commented line 4410 :
   //       nfa_match = TRUE;
  like this :
   /*       nfa_match = TRUE; */
and after modification the make works.
2b. The second error, Link phase:
--->

ld: 0711-345 Use the -bloadmap or -bnoquiet option to obtain more information.
make: The error code from the last command is 8.

Second error is the like the issue 187 :
https://code.google.com/p/vim/issues/detail?id=187  

Following up, changing the line with:
 #  define USE_UTF8_STRING 
to 
 #  undef USE_UTF8_STRING 

in vim74/src/os_unix.c completely solved the problem.

What is the expected output? 
The make command compile the sources, the text output:
##

Part 1 has just been fixed by Patch 7.4.474

Fort part 2, does this patch fix it for you?

Thanks !
I use vim console (I don't have X windows). May be adding a directive if 
defined(_AIX) somewhere to solve the problem on the line " #define 
USE_UTF8_STRING ".
To solve the link problem I changed the line :

#  define USE_UTF8_STRING 

to an undefine, like this :

 #  undef USE_UTF8_STRING 

in src/os_unix.c file.
But after tomorrow I will test the patch, with the latest source code (474).
Best regards !

The // comment line should not be there.  I tried running the tests but forgot 
to remove the line.  Fixed in patch 7.4.474.

To detect whether Xutf8SetWMProperties() actually is implemented requires a 
configure check.  Added by 7.4.475
