Hi guys,
* arm-tdep.c (arm_push_arguments): Correctly code for converting a
float argument from host format to a target double when preparing the
call frame for a function.
This works for me. Can you try it out. If it works, let me know and I'll check
it in.
Scott

Scott,
I have to try it on a few targets, so I need a few days. I will try to run all the tests this week though.
Thanks for doing this.

Here's my share of shutting up "gcc -Wall -W". Is "foo = foo;" an
okay solution for unused argument foo?
These diffs are against Feb 17 snapshot. I hope they are still
relevant and apply cleanly.
2000-02-23 Eli Zaretskii <eliz@is.elta.co.il>
* utils.c [__GO32__]: Include pc.h, for prototypes of ScreenCols
and ScreenRows.

(dpmi_regs, dpmi_sregs): Remove unused variables.
(dos_flush_input): Return a value, to prevent compiler warning.
* main.c (captured_command_loop): Prevent gcc from complaining
