Hi folks,

I uploaded a new Cygwin test release 2.6.0-0.7.

The new locale stuff has been folded into the master branch.  This
version adds the GNU-specific locale functions for converting strings to


The 2.6.0 release is going to introducing the locale_t datatype, as well
as all functions related to locale_t locales and per-thread locales per

So, rather than just providing a single, per-process locale, you can now
create new locales ("newlocale") and set it as locale for the current
thread ("uselocale") or use it directly with one of the new functions
taking a locale_t as parameter (i.e. isalpha_l).

The full list of new interfaces is:

  newlocale, freelocale, duplocale, uselocale

  isalnum_l, isalpha_l, isascii_l, isblank_l, iscntrl_l, isdigit_l,
  isgraph_l, islower_l, isprint_l, ispunct_l, isspace_l, isupper_l,
  iswalnum_l, iswalpha_l, iswblank_l, iswcntrl_l, iswctype_l,
  iswdigit_l, iswgraph_l, iswlower_l, iswprint_l, iswpunct_l,
  iswspace_l, iswupper_l, iswxdigit_l, isxdigit_l
  toascii_l, tolower_l, toupper_l, towctrans_l, towlower_l, towupper_l,
  wctrans_l, wctype_l

  strcasecmp_l, strcoll_l, strncasecmp_l, strxfrm_l

  wcscasecmp_l, wcscoll_l, wcstrncasecmp_l, wcstrxfrm_l

  strfmon_l, strftime_l

  strtol_l, stroll_l, strtoul_l, strtoull_l
  strtod_l, strtofl, strtold_l

  wcstol_l, wcsoll_l, wcstoul_l, wcstoull_l
  wcstod_l, wcstofl, wcstold_l


Since this is brand-new code, this code *will* have bugs.

It would be very helpful if interested developers and Cygwin package
maintainers could give this new stuff some good testing.

Other than that:


What changed:

- Drop support for Windows XP and Windows Server 2003/2003 R2.

- Drop support for very old SUNWNFS filesystem.

- Further header file improvements in terms of feature test macros.

- Raise number of supported partitions per disk (for raw access) to 63.
