[bug-gettext] Compile error for gettext-0.18.3.1

[Perry Smith]

I'm on AIX 6.1 TL07 SP03.  gcc is 4.5.2.  I'm doing an out of tree build.

In the build directory, I get two float.h files:

./gettext-tools/gnulib-lib/float.h
./gettext-tools/libgettextpo/float.h

which are essentially identical.

They define union gl_long_double_union which upsets the compiler when both 
copies are included.  This may be an issue way further up stream in the build 
process.  I see these files come from:

gettext-tools/gnulib-lib/float.in.h
gettext-tools/libgettextpo/float.in.h

which are identical.  I think the text from the build that you need is:

Line 302 of limits.h has:

#include <float.h>

I cobbled around it by doing this:

>   # define LDBL_MAX (gl_LDBL_MAX.ld)
>   #endif


in both files.  It may be that float.h needs to be renamed if it is going to 
conflict with an existing file.  Fun fun fun building on AIX :-)

I am not sure if I am subscribed to this list or not.  If you need help in 
debugging this, drop me a direct email.

Good luck and thank you,
