Main.cpp contains a test:

#ifdef HAVE_IEEEFP_H
#include <ieeefp.h>
#endif

and, in /usr/ports/graphics/inkscape/work/inkscape-0.92.2/include/config.h is
found

/* Define to 1 if you have the <ieeefp.h> header file. */
#define HAVE_IEEEFP_H 1

so it looks as if the test is satisfied.

A brute-force search of the filesystem discloses several copies of ieeefh.h:
/tmp/mountpoint.Jw2teE/www/firefox-esr/work/firefox-52.5.2esr/obj-armv7-unknown-freebsd12.0/config/system_wrappers/ieeefp.h
/usr/include/machine/ieeefp.h
/usr/include/ieeefp.h
/usr/obj/usr/src/arm.armv7/tmp/usr/include/machine/ieeefp.h
/usr/obj/usr/src/arm.armv7/tmp/usr/include/ieeefp.h
/usr/obj/arm.armv7/usr/src/tmp/usr/include/machine/ieeefp.h
/usr/obj/arm.armv7/usr/src/tmp/usr/include/ieeefp.h
/usr/src/sys/arm/include/ieeefp.h
/usr/src/sys/amd64/include/ieeefp.h
/usr/src/sys/arm64/include/ieeefp.h
/usr/src/sys/mips/include/ieeefp.h
/usr/src/sys/i386/include/ieeefp.h
/usr/src/sys/powerpc/include/ieeefp.h
/usr/src/sys/sparc64/include/ieeefp.h
/usr/src/sys/riscv/include/ieeefp.h
/usr/src/include/ieeefp.h
^C

It's clear the file is present. All the other include files seem to be 
found, so it's not an obvious search path defect.

Thanks for reading, and any further thoughts!
