The official guideline for building fftw on windows is outdated, I consider BUILD-MINGW32 and BUILD-MINGW64 and PKGBUILD as a better reference.

On win32, some versions of gcc assume that the stack is 16-byte aligned, but code compiled with other compilers may only guarantee a 4-byte alignment, resulting in mysterious segfaults.

As quoted, --with-incoming-stack-boundary=2 is only applicable to win32(x86), not x64.

configure:15780: checking whether C compiler accepts -mincoming-stack-boundary=2
configure:15795: gcc -c -mincoming-stack-boundary=2  conftest.c >&5
cc1.exe: error: -mincoming-stack-boundary=2 is not between 3 and 12
