gcc - compile 32bit code from cygwin64 -

i installed cygwin64 on win7-64 gcc dev tools , noticed produces 64bit binaries. (well, not surprising :o) there mean make producing 32bit binaries?

i compiling socat tool windows, compiled in 64bit working, trying make version suitable xp-32.

the configure script not seem support -b 32 switch (that must have seen ming64 this thread, , if try specify -m32 switch in cflags configure fails:

$ cflags=-m32 ./configure checking defines needed makedepend... checking bsd-compatible install... /usr/bin/install -c checking gcc... gcc checking whether c compiler works... no configure: error: in `/cygdrive/c/dev/tools/nettools/socat/socat-2.0.0-b8': configure: error: c compiler cannot create executables see `config.log' more details 

would option install cygwin32, or can compile 32bit code setting or additional cygwin package?

edit: have found cygwin64/gcc cannot compile simple hello.c program in 32bits:

#include <stdio.h>  int main (int argc, char *argv[]){     printf("hello, world!\n");     return 0; } 

with gcc -o hello.exe hello.c works flawlessly, gcc -o hello.exe hello.c -m32 spits

cygwin provides packages containing cygwin-to-cygwin cross toolchains. there cygwin32-* packages building 32-bit 64-bit cygwin , cygwin64-* packages building 64-bit 32-bit cygwin.

i've never used them, assume work pretty cross toolchain, should pass correct --host , --build arguments ./configure step.
