Summary: Compiler command percent-sign causes format string error

Initial Comment:
[From a question posted to python-help]

Using Sun's compiler, distutils generates a command line with a 
percent-sign in it:

cc -DNDEBUG -xO3 -xtarget=native -xbuiltin=%all -xdepend=yes -
xlibmil -xlibmopt -xstrconst -Xa -I/opt/pkg/include/db4 -I/usr/
include -I/opt/pkg/include -xcode=pic32 -OPT:Olimit=0 -I. -I/opt/
pkg.obj/lang/python24/work.e450/Python-2.4.3/./Include -I/opt/
pkg/include -I/opt/pkg.obj/lang/python24/work.e450/Python-2.4.3/
Include -I/opt/pkg.obj/lang/python24/work.e450/Python-2.4.3 -c /
opt/pkg.obj/lang/python24/work.e450/Python-2.4.3/Modules/
structmodule.c -o build/temp.solaris-2.10-sun4u-2.4/structmodule.o

It seems that the percent-sign in "-xbuiltin=%all" isn't escaped when 
distutils goes to print the line and a format string error occurs:

File "/opt/pkg.obj/lang/python24/work.e450/Python-2.4.3/Lib/
distutils/log.py", line 23, in _log
    print msg % args
TypeError: not enough arguments for format string
*** Error code 1

Here's the full traceback:

asked about it on python-help.)
