Whoa, this may not generalise to "all" Solaris machines.

(Seems not all Solaris's are equal then - Dean's machine
is certainly different than mine).

I get a proper response from an SS4 and an Ultra-1:

SS4:
	# uname -a
	SunOS srv 5.5.1 Generic sun4m sparc SUNW,SPARCstation-4

	using either gcc or cc (/usr/ucb/cc)  I get:

	# gcc -o pwtest pwtest.c
	# ./pwtest 
	getpwnam(" jmack") -> USER UNKNOWN

	# cc -o pwtest pwtest.c
	# ./pwtest
	getpwnam(" jmack") -> USER UNKNOWN

Ultra-1:
	# uname -a
	SunOS tuzo 5.5 Generic sun4u sparc SUNW,Ultra-1

	# ./pwtest 
	getpwnam(" jmack") -> USER UNKNOWN

(perhaps there is something wonky with libc on Dean's machine?)

Cheers,
