problem building on AIX 4

[Bruno Haible]

Hi,

I'm trying to build coreutils-6.12.29-a16be on AIX 4.3.2. It was built
with autoconf 2.62.

$ ./configure
...
$ make
"Makefile", line 541: make: 1254-055 Dependency line needs colon or double 
colon operator.
"Makefile", line 542: make: 1254-055 Dependency line needs colon or double 
colon operator.
...
make: 1254-058 Fatal errors encountered -- cannot continue.

The Makefile contains this at line 540ff:

As you can see, there is a problem with missing backslashes.

Makefile.in has this:

-------------------------------------
MAN = @MAN@
MKDIR_P = @MKDIR_P@
-------------------------------------

config.status has this:

The problem lies in the second MAN assignment in configure.ac:

MAN=`for m in $MAN; do test $m = ginstall.1 && m=install.1; echo $m; done \
  | tr '\015\012' ' '; echo`

On Linux:
$ MAN="abc.1 def.1 "; for m in $MAN; do echo $m; done | tr '\015\012' ' '; echo
abc.1 def.1 

On AIX:
$ MAN="abc.1 def.1 "; for m in $MAN; do echo $m; done | tr '\015\012' ' '; echo
abc.1
def.1

The fix is to change the second argument of the 'tr' command from a single space
to a double space; then it works.
