_ctype_ not exported by cygwin1.dll ??

[John Fortin <fortinj@ibm.net>]

I seen this topic discussed, read the archives and I am still confused
about _ctype_

I see that in ctype.h _ctype_ is as follows...

#if !defined(__CYGWIN32__) || defined(__INSIDE_CYGWIN__) ||
defined(_COMPILING_NEWLIB)
extern	_CONST char	_ctype_[];
#else
extern	_CONST char	_ctype_[] __declspec(dllimport);
#endif

I take this to mean that for compiled programs, _ctype_ is exported from
cygwin1.dll

I looked at both the dll and the export library and _ctype_ seems to be
there.

I am using the newest snapshots for winsup (July 5 ) and newlib ( July 3
)

So I can't explain the following....
