I got a nice simple response from a friend on another forum. (I can't be sure he didn't cheat and just post the answer from the K&R answer book, but I'll give him the benefit of the doubt)
Code:
int main()
{
c = getchar();
while (c != EOF)
{
putchar(c);
do
{
c = getchar();
} while ( c != EOF && c == ' ');
}
return 0;
}
Although I'm not yet used to the do-while construct, I can see where it works very nicely here. It checks the condition after executing the statements inside the loop. I think this is somewhat like Bash's do-until structure (although I've never used that). Just thought I'd share. Now onto the other problems in the chapter.

fgetc
GETC(3) BSD Library Functions Manual GETC(3)NAME
fgetc, getc, getc_unlocked, getchar, getchar_unlocked, getw -- get next character or word from input stream
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <stdio.h>
int
fgetc(FILE *stream);
int
getc(FILE *stream);
int
getc_unlocked(FILE *stream);
int
getchar(void);
int
getchar_unlocked(void);
int
getw(FILE *stream);
DESCRIPTION
The fgetc() function obtains the next input character (if present) from the stream pointed at by stream, or the next character pushed back on
the stream via ungetc(3).
The getc() function acts essentially identically to fgetc(), but is a macro that expands in-line.
The getchar() function is equivalent to getc(stdin).
The getw() function obtains the next int (if present) from the stream pointed at by stream.
The getc_unlocked() and getchar_unlocked() functions are equivalent to getc() and getchar() respectively, except that the caller is responsi-
ble for locking the stream with flockfile(3) before calling them. These functions may be used to avoid the overhead of locking the stream
for each character, and to avoid input being dispersed among multiple threads reading from the same stream.
RETURN VALUES
If successful, these routines return the next requested object from the stream. Character values are returned as an unsigned char converted
to an int. If the stream is at end-of-file or a read error occurs, the routines return EOF. The routines feof(3) and ferror(3) must be used
to distinguish between end-of-file and error. If an error occurs, the global variable errno is set to indicate the error. The end-of-file
condition is remembered, even on a terminal, and all subsequent attempts to read will return EOF until the condition is cleared with
clearerr(3).
SEE ALSO ferror(3), flockfile(3), fopen(3), fread(3), getwc(3), putc(3), ungetc(3)STANDARDS
The fgetc(), getc(), and getchar() functions conform to ISO/IEC 9899:1990 (``ISO C90''). The getc_unlocked() and getchar_unlocked() func-
tions conform to IEEE Std 1003.1-2001 (``POSIX.1'').
BUGS
Since EOF is a valid integer value, feof(3) and ferror(3) must be used to check for failure after calling getw(). The size and byte order of
an int varies from one machine to another, and getw() is not recommended for portable applications.
