Latest version of cygwin; Building kdevelop 4.7.x

[Michael George Hart]

I have gotten the latest version of cygwin and been attempting to build the
latest version of kdevelop 4.7.x

I managed to figure that the following get me pretty far, the 53% build
marker for
KDevPlatform:

     cmake -DCMAKE_INSTALL_PREFIX=/usr/local/kdevelop4
-D__KDE_HAVE_GCC_VISIBILITY=NO ../
     make

Has anyone successfully build kdevelop 4.7.x under cygwin; I have the
latest download of cygwin with gcc 5.3

I get the following compile errors that would indicate that the cygwin is
neither POSIX or BSD, (which seems strange since I am able to run a number
of KDE application under cygwin X KDE windows openbox)

gettimeofday, timersub (see http://linux.die.net/man/3/timersub).

Setting -fpermissive does not stop the error as implied by the generated
error message above

The multiple parameter version of setenv does not seem to be availability
under cygwin
int setenv(const char *name, const char *value, int overwrite);

As the setenv documentation says
"_POSIX_C_SOURCE >= 200112L
               || /* Glibc versions <= 2.19: */ _BSD_SOURCE"
(See http://man7.org/linux/man-pages/man3/setenv.3.html)

My work environment limits me to what I can do on the windows; no admin
rights. However  we are allowed to install the latest version of cygwin,
which happens to have gcc 5.3 compiler and install or build from source
what ever we happen to be able to down from zip, tar files etc.

I really would like to continue working in a Linux like environment

Thanks for listening and any help that maybe available
