Re: gcc -ansi produces unexpected floating point result

try gcc4, gcc3 is obsolete.

Hi Marco.

Unfortunately gcc-4 gives this error:

C:\devel\bwbasic>gcc-4 -mno-cygwin -ansi zatest.c
gcc-4: The -mno-cygwin flag has been removed; use a mingw-targeted

Hi Paul, gcc4 is for building on cygwin for cygwin.

-mno-cygwin was for building on cygwin for NO cygwin, like mingw.
It is now a deprecated tweak.

For that scope are now available 2 cross-compilers
see packages:


both as 4.5.x versions

I'm also including the results of ldd on the gcc3 compile:

C:\devel\bwbasic>ldd a.exe
        ntdll.dll => /cygdrive/c/Windows/SysWOW64/ntdll.dll (0x77e70000)
        kernel32.dll => /cygdrive/c/Windows/syswow64/kernel32.dll
        KERNELBASE.dll => /cygdrive/c/Windows/syswow64/KERNELBASE.dll
        msvcrt.dll => /cygdrive/c/Windows/syswow64/msvcrt.dll (0x75a60000)

It looks to me like I have done everything correctly, and it would
be good if gcc 3 still worked. gcc 3 is important to me for other
reasons (ie it is the only thing that supports the i370 target).

I don't have any other platform to try gcc 3.4.4 out on.

Thanks. Paul.

Regards Marco
