[Linux] MB_LEN_MAX incorrect
----------------------------

                 Key: STDCXX-436
                 URL: https://issues.apache.org/jira/browse/STDCXX-436
             Project: C++ Standard Library
          Issue Type: Bug
          Components: 18. Language Support
    Affects Versions: 4.2
         Environment: gcc version 4.1.1 20070105 (Red Hat 4.1.1-51)
            Reporter: Mark Brown


On my Linux system MB_LEN_MAX is normally defined to 16 but when I use the macro in a program compiled with stdcxx the macro evaluates to 1. The test case goes like this:

$ cat test.cpp && make CPPOPTS="-DGETCONF_MB_LEN_MAX=`getconf MB_LEN_MAX`" test && ./test
#include <assert.h>
#include <limits.h>

int main ()
{
    assert (MB_LEN_MAX == GETCONF_MB_LEN_MAX);
}
gcc -c -I/home/mbrown/stdcxx/include/ansi -D_RWSTDDEBUG    -I/home/mbrown/stdcxx/include -I/home/mbrown/stdcxx-gcc-4.1.1-11s/include -I/home/mbrown/stdcxx/examples/include -DGETCONF_MB_LEN_MAX=16 -pedantic -nostdinc++ -g  -W -Wall -Wcast-qual -Winline -Wshadow -Wwrite-strings -Wno-long-long -Wcast-align   test.cpp
gcc u.o -o u  -L/home/mbrown/stdcxx-gcc-4.1.1-11s/lib  -lstd11s -lsupc++ -lm 
test: test.cpp:6: int main(): Assertion `1 == 16' failed.
Aborted
