It told me to report it.

Building ImageMagick 5.5.6 on AIX using the AIX c compiler gets me the 
following:

configure: WARNING: jpeglib.h: accepted by the compiler, rejected by the 
preprocessor!
configure: WARNING: jpeglib.h: proceeding with the preprocessor's result
configure: WARNING:     ## ------------------------------------ ##
configure: WARNING:     ## Report this to address@hidden ##
configure: WARNING:     ## ------------------------------------ ##
checking for jpeglib.h... no

which is caused by the fact that I set the CFLAGS to have a -I argument, 
but the cc -E test doesn't include CFLAGS.
