>Description:

Although I have

/usr/local/include/X11/extensions/Print.h

and

/usr/local/lib/libXp.a		/usr/local/lib/libXp.so
/usr/local/lib/libXp.la		/usr/local/lib/libXp.so.6

installed (they also look sane), configure fails t
detect them properly.

>From config.log:

configure:18905: cc -o conftest -O2 -pipe -march=nocona -fno-strict-aliasing -st
d=gnu89 -Wall -g -fno-strict-aliasing -Wno-unused -Wno-comment -fno-tree-ter -DC

configure:18912: $? = 0
configure:18943: result: -liconv
configure:19054: checking for libXp

conftest.c:109:34: error: X11/extensions/Print.h: No such file or directory

What happens is that at some point configure gets lost in saving/restoring
CFLAGS/LDFLAGS and forgets to use -I/usr/local/include and -L/usr/local/lib

it looks like that 

checking for XmuNCopyISOLatin1Lowered  in -lXmu... 

still has our custom flags, while the next test

checking for dirent.h that defines DIR... 

forgets the flags.
