Here is another variant of a libgd problem:

gcc memusagestat.c -c -O -Wall -Winline -Wstrict-prototypes -Wwrite-strings -g      -I../include -I.  -I.. -I../libio  -I../sysdeps/mips/elf -I../linuxthreads/sysdeps/unix/sysv/linux -I../linuxthreads/sysdeps/pthread -I../linuxthreads/sysdeps/unix/sysv -I../linuxthreads/sysdeps/unix -I../linuxthreads/sysdeps/mips -I../sysdeps/unix/sysv/linux/mips -I../sysdeps/unix/sysv/linux -I../sysdeps/gnu -I../sysdeps/unix/common -I../sysdeps/unix/mman -I../sysdeps/unix/inet -I../sysdeps/unix/sysv -I../sysdeps/unix/mips -I../sysdeps/unix -I../sysdeps/posix -I../sysdeps/mips/fpu -I../sysdeps/mips -I../sysdeps/wordsize-32 -I../sysdeps/ieee754/flt-32 -I../sysdeps/ieee754/dbl-64 -I../sysdeps/ieee754 -I../sysdeps/generic/elf -I../sysdeps/generic  -nostdinc -isystem /usr/lib/gcc-lib/mips-linux/2.96/include -isystem /usr/src/linux-2.4/include -D_LIBC_REENTRANT -include ../include/libc-symbols.h  -DPIC   -o memusagestat.o
memusagestat.c:36:16: gd.h: No such file or directory
memusagestat.c:37:21: gdfontl.h: No such file or directory
memusagestat.c:38:21: gdfonts.h: No such file or directory
make: *** [memusagestat.o] Error 1

These three files do exist in /usr/include/ but thanks to -nostdinc we're
not even searching there.

These options are used due to the configure option --with-headers=/usr/
src/linux-2.4/include.  Configure doesn't use the same options when searching
for libgd so it finds the libraries in /usr/include or in <prefix>/<target>/
include/ for crosscompilers.

In that context I noticed that this configure help:

  --with-headers=PATH     location of system headers to use
                          [e.g. /usr/src/linux/include]
                          [default=compiler default]

may be missunderstood.  The example seems to indicate that only kernel
headers will be searched there.  So I'm somewhat unsure about the original
intentsion how all this was supposed to work and therefore don't know how
exactly to fix this.
