Content-Type: text/plain; charset=UTF-8

Based on the output of the identify-compilers.sh script below, it
appears that the following C compilers are available on Cygwin. Those
labeled "Cygwin" require the cygwin1.dll file to be available.

What is the difference between the "pc" and "w64" compilers?

Why is there no x86_64-pc-mingw-gcc.exe executabe?

Are there any other C compilers available?

/usr/bin/gcc.exe                        64-bit  Cygwin
/usr/bin/i686-pc-cygwin-gcc.exe         32-bit  Cygwin
/usr/bin/i686-pc-mingw32-gcc.exe        32-bit
/usr/bin/i686-w64-mingw32-gcc.exe       32-bit
/usr/bin/x86_64-pc-cygwin-gcc.exe       64-bit  Cygwin
/usr/bin/x86_64-w64-mingw32-gcc.exe     64-bit

$ cat identify-compilers.sh
#!/bin/bash
for c in $(ls -1 /usr/bin/*gcc.exe); do
    echo === compiler: $c
    $c -o hello.exe hello.c
    objdump -p hello.exe | grep -i "cygwin"
    objdump -p hello.exe | grep -i "64$"
    rm hello.exe
done
