Additional cygwin packages needed and runtime problem

I built the rtems and bare tool chains on Fedora linux with no problem.
Wanted to also see if they would build on cygwin under Windows 10. After
checking that all the listed cygwin packages were installed, I began the
build. Finished gcc/newlib and when building gdb I discovered that two
cygwin packages were needed that were not listed in the
libncurses-devel (only needed for bare, rtems tools built OK w/o this)
These probably should be added to the required cygwin packages in the
After the cygwin build finished I tried to run the installed gcc.exe
binary in fedora under wine. It appears that the gcc binary is not mingw
but a cygwin binary since the cygwin1.dll is required and is missing:
[gene at hplt bin]$ ./arm-rtems4.12-gcc.exe --version

containing experimental patches.

This works OK in fedora/wine for other mingw based toolchain, i.e.,
Codesourcery with no dependencies on cygwin dll's.
I will try the "recommended" msys build method and see if it works better.
