Why did you upgrade only to 3.2? We are currently using gcc-4.2.2. You
are welcome to download ELDK 4.2 for arm[1] and give it a try.

You expected new errors? Uh uh, I was hoping for them to go away ;)

I don't understand this. include/common.h defines U_BOOT_CMD to take 6
parameters. Your example common/cmd_boot.c also provides 6 parameters:
U_BOOT_CMD(
bootm, CONFIG_SYS_MAXARGS, 1, do_bootm,
"boot application image from memory",
"[addr [arg ...]]\n - boot application image stored in memory\n"
"\tpassing arguments 'arg ...'; when booting a Linux kernel,\n"
...... [more concatenations below this point]
So I count 4 parameters on the first line, 1 parameter on the next and
the 6th parameter is the long list of concatenated strings.
Why should you need to add another parameter here?

The easiest way would be to upgrade to a _recent_ toolchain (i.e. >4).
On the other hand, the line you mention was added in this commit:
http://git.denx.de/?p=u-boot.git;a=commit;h=f62fb99941c625605aa16a0097b396a5c16d2c88
If you check the commit msg, you get an idea of how you may "unwind"
this optimization.
However, why invest time, if a recent toolchain "just works"?

It should be enough to #undef CONFIG_CMD_NAND in the config file.
