MinGW release running out of command line before passing to GCC?

MinGW release running out of command line before passing to GCC?

Hi,

I'm running 3.09 MinGW.  When trying to compile like this...

ocamlopt.opt -warn-error A -I . -o A.opt unix.cmxa str.cmxa nums.cmxa
libB.cmxa A.cmx

...I get this error...

gcc: @F:\DOCUME~1\user\LOCALS~1\Temp\camlresp33a735: Invalid argument
Error during linking

When I fiddle around with it, I discover that the problems come when I add
another object to be linked.  This can be either my own binary or one of the
Caml included libraries.

Can anyone explain why this might be, and what I can do to remedy it?

You're using a set of MinGW compilers that do not understand the
@responsefile notation for bypassing Window's stupidly low limits on
command-line length.

See the installation instructions (file README.win32), paragraph
starting with "Do *not* install the Mingw/MSYS development tools from
www.mingw.org".

Hi,

this patch fixed it for me:
