Thes following describes a problem I am seeing with collect2.exe
apparently not picking up the fact that a module exists within a
library.

I am attempting to build Microwindows v0.89pre7, with DJGPP v203 under
Windows 95.

I hope someone here will be able to explain what's going on.....

In the linking process DJGPP runs:
c:/djgpp/lib/gcc-lib/djgpp/2.952/collect2.exe -o mdemo
c:/djgpp/lib/crt0.o -Lc:/soft/dev/microwin/src/lib -Lc:/djgpp/lib
-Lc:/djgpp/lib/gcc-lib/djgpp/2.952 -Lc:/djgpp/bin -Lc:/djgpp/lib -lgrx20
mdemo.o c:/soft/dev/microwin/src/lib/libmwin.a
c:/soft/dev/microwin/src/lib/libmwinlib.a
c:/soft/dev/microwin/src/lib/libmwengine.a
c:/soft/dev/microwin/src/lib/libmwdrivers.a
c:/soft/dev/microwin/src/lib/libmwfonts.a
c:/soft/dev/microwin/src/lib/libmwimages.a -lgrx20 -lgcc -lc -lgcc
-Tdjgpp.djl c:/soft/dev/microwin/src/lib/libmwinlib.a

and gives:
(edit.o)(.text+0x6f6):edit.c: undefined reference to `CreateFont'

'CreateFont' is in winfont.o, which is in libmwin.a.
bash-2.04$ ar -t libmwin.a
winmain.o
winuser.o
wingdi.o
winexpos.o
winclip.o
winevent.o
windefw.o
winrgn.o
winfont.o
winsbar.o

edit.o is in libmwinlib.a
bash-2.04$ ar -t libmwinlib.a
draw3d.o
ptinsid.o
insetr.o
fastfill.o
graph3d.o
mwuser.o
button.o
edit.o
listbox.o
progbar.o
static.o
combobox.o
caret.o
scrlbar.o
medit.o

If I suffix the (long) command with
'c:/soft/dev/microwin/src/mwin/winfont.o' (to specify another object to
add) then it builds and runs.... very strange!!
