Use the functions in include/asm-i386/string-486.h
Although the call 'strstr' does not appear in string.h it is in this
file.
These functions are written in 486 assembly code and thus completely
independent of Linux. That is if you are using a 486 or better. If you
are using a different architecture look for a similar file in your asm
directory to see if 'strstr' is supported.
