On Linux and in Mingw-w64, fexcept_t is defined as type unsigned short.
There are packages in the wild which rely on the fact that fexcept_t is
an integral type. We're changing the internal handling to use the bits
just as in GLibc, so only the 6 lowest bits are used to reflect the hw
bits. We even change the header file guard to reflect GLibc for compatibility.
* include/fenv.h (_FENV_H): Rename from _FENV_H_ and set to 1 as in
GLibc's header.
(fexcept_t): Change to __uint16_t to be an integral type as in GLibc.
* fenv.cc (fegetexceptflag): Align to the *flagp's type change.
(fesetexceptflag): Ditto.

This patch adds the long double functions missing in newlib to Cygwin.
Apart from some self-written additions (exp10l, finite{f,l}, isinf{f,l},
isnan{f,l}, pow10l) the files are taken from the Mingw-w64 math lib.
Minor changes were required, e.g. substitue _WIN64 with __x86_64__ and
fixing __FLT_RPT_DOMAIN/__FLT_RPT_ERANGE for Cygwin.
Cygwin:
* math: New subdir with math functions.
* Makefile.in (VPATH): Add math subdir.
(MATH_OFILES): List of object files collected from building files in
math subdir.
(DLL_OFILES): Add $(MATH_OFILES).
${CURDIR}/libm.a: Add $(MATH_OFILES) to build.
* common.din: Add new functions from math subdir.
* i686.din: Align to new math subdir. Remove functions now commonly
available.
* x86_64.din: Ditto.
* math.h: math.h wrapper to define mingw structs used in some files in
math subdir.
* include/cygwin/version.h: Bump API minor version.
newlib:
* libc/include/complex.h: Add prototypes for complex long double
functions. Only define for Cygwin.
* libc/include/math.h: Additionally enable prototypes of long double
functions for Cygwin. Add Cygwin-only prototypes for dreml, sincosl,
exp10l and pow10l. Explain why we don't add them to newlib.
* libc/include/tgmath.h: Enable long double handling on Cygwin.

The inclusion of <sys/cygwin.h> by <sys/shm.h>, besides causing namespace
pollution, also makes it very difficult to get the WINVER-dependent parts
of the former. This affects code (such as x11vnc -unixpw_nis) which use
both SysV shared memory (e.g. the X11 MIT-SHM extension) and user password
authentication.
getpagesize is the simplest function to retreive this information, but it
is a legacy function and would also pollute the global namespace. The LSB
lists another form which is in the implementation-reserved namespace:

Don't use u_char, u_short, u_int or u_long in Cygwin, unless it refers

u_char, u_short, u_int, u_long are BSD-only types. Remove them from
Cygwin headers which are supposed to be used in a non-BSD scenario.
Drop special Cygwin handling of those types in sys/types.h.
newlib:
* libc/include/sys/types.h (u_char,u_short,u_int,u_long): Drop
Cygwin exception.
cygwin:
* fhandler_socket.cc (fhandler_socket::ioctl): Accommodate change
in include/asm/socket.h. Continue using u_long since that's the
MS type here.
* include/asm/socket.h: Since the type given in _IOR/_IOW macros
is only used for its sizeof, replace u_long with equivalent long.
* netdb.h (getnetbyaddr): Fix prototype.
* netinet/ip.h: Replace old BSD-only types with generically defined
old BSD types (u_char -> u_int8_t, etc).
* netinet/tcp.h: Ditto.

The u_intN_t types are BSD types but sanctioned by POSIX. They are

So far any group in the user's token could be used as primary group.
Windows doesn't check if the primary group is enabled or not, it just

A user token can be up to 64K in size. Using 32K buffers for TOKEN_GROUPS

A user token can be up to 64K in size. The group list might take a lot
of that so use tmp_pathbuf allocated space rather than stack space
allocted via alloca. In create_token the TOKEN_GROUP was allocated via
malloc, but the code is needlessly complicated. Simplify by using
tmp_pathbuf as well.
* sec_auth.cc (verify_token): Allocate TOKEN_GROUP via tmp_pathbuf.
