I tried it:

I looked at the source file names, found some good looking files and with
-mmcu=msp430xW427 and #include <msp430xW42x.h> the MCU is known, so the above
error list is wrong.
I could start compiling but with the new MCU type i do get many errors:
main.c:69: `CACTL2' undeclared (first use in this function)
...
main.c:71: `CAON' undeclared (first use in this function)
isr.c:109: `CACTL1' undeclared (first use in this function)
...
modules.c:789: `CAF' undeclared (first use in this function)
...
make: *** [main.o] Error 1
What's wrong?

Yes, for F413.

Yes, with -O2 it's bigger.
I'm using
CPU = msp430xW427
ASMOPT = -mmcu=${CPU} -std=gnu99 -ffunction-sections -fgcse -fssa
-fdelete-null-pointer-checks -fno-math-errno -mno-stack-init -Os
-mendup-at=main -Wall
COPT = -mmcu=${CPU} -std=gnu99 -Os -mendup-at=main -Wall -g
> - does the code use floats?
Yes.
Does mspgcc produces more float code than the IAR compilers?
By the way: I've done a simple install script which can be used for a coffee
break during installation and which makes installation easier and less
error-prone:
#!/bin/bash
#
# Simple install script for mspgcc with hard coded versions.
# Use it as user root(.root) as
# ./build_mspgcc.sh 2>&1 | tee build_mspgcc.out
# which will create build_mspgcc.out as the log file.
#
# It takes approx. 9 minutes with a 2 GHz 32 bit CPU.
