With the "original" GNU Emacs 25.0.50 the first problem these two compilers have is libjpeg 9b. Configure only finds:

	configure:14428: WARNING: libjpeg found, but not version 6b or later 

Later, when "checking for EGifPutExtensionLast in -lgif," it finds:

	configure:14871: error: The following required libraries were not found:
	     libjpeg
	Maybe some development libraries/packages are missing?
	If you don't want to link with them give
	     --with-jpeg=no
	as options to configure

So, configuring with --with-jpeg=no I can build GNU Emacs – almost:

The config.log files are saved. After dinner I'll check with GNU Emacs 26.0.90.

The box said "Use Windows 95 or better," so I got a Macintosh.
