Port Notes:

----- version 3.1.0-EL-3  -----
Rebuild only for x86_64
autotools reapplied
src/Makefile needs to be modified after configure:
> X_LIBS = -lglut -lXi -lXext -lXmu -lGLU -lGL  -lXt -lX11
> libgle_la_LDFLAGS = -version-info 4:0:1 -no-undefined -export-dynamic $(X_LIBS)



----- version 3.1.0-EL-2  -----
Rebuild with --prefix=/usr
Rebuild autostuff with latest libtool
In top dir commented out DEBUG_OUTPUT (this is an error in configure?)
In src changed LDFLAGS to '-no-undefined -export-dynamic -lglut -lXi -lXext -lXmu -lGLU -lGL  -lXt -lX11' to have the dll built

----- version 3.1.0-EL-1  -----
Initial release

Finaly 'Hand made' the dll because I spent to mush time to understand
how it can be done. Maybe someone later ????

cd src/.libs
gcc -shared -Wl,-export-all -Wl,--out-implib=libgle.dll.a -o cyggle-3.dll ex_alpha.o ex_angle.o ex_cut_round.o ex_raw.o extrude.o intersect.o qmesh.o rot_prince.o rotate.o round_cap.o segment.o texgen.o urotate.o view.o -L/usr/X11R6/lib -lGL -lglu

Will produce:
-rw-r--r--    1 lassauge lassauge    40022 Jan 28 18:02 libgle.dll.a
-rwxr-xr-x    1 lassauge lassauge   119927 Jan 28 18:02 cyggle-3.dll

All that was later preinstalled 'by hand' too.
