Subject: coreutils-8.29 compilation failure using xlC on AIX

[Message part 3 (text/plain, inline)]

Build environment:
coreutils-8.29
AIX 6.1
xlC version:
    IBM XL C/C++ for AIX, V12.1 (5765-J02, 5725-C72)
    Version: 12.01.0000.0002
AIX make (/bin/make)


Environment variables:
export CC=xlC
export CFLAGS=-q64
export CXX=$CC
export CXXFLAGS=$CFLAGS
export LD=ld
export AR="ar -X64"
export LDFLAGS="-Wl,-bmaxdata:0x80000000"

Bug:
./configure succeeds
make fails:
    CC       src/stat.o
    "src/stat.c", line 598.19: 1506-045 (S) Undeclared identifier intmax_bufsize.
    "src/stat.c", line 598.19: 1506-1324 (S) Array size must have integer type.
Problematic code in src/stat.c:
    enum { intmax_bufsize = INT_BUFSIZE_BOUND (intmax_t) };
    static char str[intmax_bufsize ...


Description:
I see this enum technique used in slightly different ways in other parts of the source.  

I'm not sure of the rationale for using enum here, but apparently the AIX xlC compiler
doesn't like it.  Since it is the only use of this variable (intmax_bufsize) in this 

file, it is easy to replace the use of intmax_bufsize with its value INT_BUFSIZE_BOUND(intmax_t),
which allows the compilation to finish correctly.  I'm not aware of any other 

workaround for this issue.  Maybe it's a compiler bug?  But in any case, it would be 

nice if a source change didn't have to be made.

As an additional comment, it took me quite a while to find working values for
CFLAGS, AR, and LDFLAGS.  I'm not sure how you might accomplish it, but it would be
friendlier if, once it's determined that gcc is not available and xlC is available,
a reasonable set of default options were supplied, so that every user of xlC doesn't
have to rediscover some set defaults which allow the build to succeed.

Finally, I'm attaching the test-suite.log indicating a couple of failures and a few errors.

... and I'm marking the bug as done.
