TDM64 is bi-arch gcc distribution with unusual configuration : 32-bit compiler produces 64-bit object files / executables by default, -m32 is required for 32-bit compilation.
See http://tdm-gcc.tdragon.net/quirks for details.
There are few places in Go source tree where C compiler name and required switches ( in particular -m32/-m64 ) are not obtained from environment variables or by running go env :
on tip in src/runtime/syscall_windows_test.go
initialization of cbDLLs variable
C compiler run in function TestReturnAfterStackGrowInCallback
test for C compiler availability in TestStdcallAndCDeclCallbacks and TestReturnAfterStackGrowInCallback
on 1.4.2
in src/make.bat
in src/runtime/syscall_windows_test.go : initialization of cbDLLs variable
in misc/cgo/testso/test.bat
As a result you simply can't build 1.4.2 using TDM64 on 32-bit Windows : compiled dist.exe is 64-bit.
On tip runtime test fails because of 64-bit test.dll :
