I think I expressed myself incorrectly or I am not able to be
understood, no matter what package I choose. gcc-core does not compile
using the cygwin dll, the one that compiles for that library is cygwin-
gcc.
now I will try to explain my case better,
1 when I use the gcc-core package if it is able to detect the whole
set, the only thing that happens is that the script does not recognize
cygwin nt as a valid operating system.
2 when I use the mingw64-x86_64-gcc package it is not able to compile
without add-ons.
for example when I compile with gcc-core if it is able to detect the
libcaca-devel library, this is the library that qemu asks me for sd-
card support,
However, when I use the package mingw64-x86_64-gcc it is not able to
find it in the system because it is not in its set, for this it is
mandatory to use the gcc-core package (not cygwin-gcc), I do not want
to use linux, I want to keep him as far away from my team as possible,
just because I work for him doesn't mean I want him
