Stop using cat! The grep utility is perfectly capable of opening files by itself and doing it that way is not only MUCH more efficient, it also gets rid of all of your problems. Try:
Code:
find . -type f -exec grep "make" {} \;

or if you want the grep output to let you know which file(s) contain the word you are trying to find; and since you're looking for a fixed string you can make the search much faster with:
Code:
find . -type f -exec grep -F "make" /dev/null {} +

which looks for fixed strings (instead of regular expressions) in large numbers of files with each invocation of grep (instead of one invocation of grep for each file processed).
What's the difference between {} \; and {} + or {} \+ ?

Is it possible to call multiple commands with -exec like piping:
Code:
find . -type f -exec onecommand | secondcommand {} \;

What's wrong with using cat?

zgrep

ZGREP(1)						      General Commands Manual							  ZGREP(1)

NAME

       zgrep - search possibly compressed files for a regular expression

SYNOPSIS

       zgrep [ grep_options ] [ -e ] pattern filename...

DESCRIPTION

       Zgrep  invokes  grep  on  compressed  or  gzipped  files.   These  grep	options  will  cause  zgrep  to  terminate  with  an  error  code:
       (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*).  All other options specified are passed directly to grep.  If no file is specified,  then  the
       standard input is decompressed if necessary and fed to grep.  Otherwise the given files are uncompressed if necessary and fed to grep.

       If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.

EXIT CODE

       2 - An option that is not supported was specified.
