Tom,

thanks for answering so quickly.

I have tried several places for the win32ada.lib at the libs.ld and
still no results. The mktest uses the following commands:

gcc -c test_assert.adb
gnatbl test_assert.ali ..\lib\win32ada.lib -o test_ass.exe

So I think the win32ada.lib was referenced too by the linker. I even
placed the win32ada.a at the beginning of the libs.ld file (you never
know). When trying to build the test_stdio.adb (for the experiments I
focus on test_assert.adb)  I even got more errors, meaning undefined
references to:
_fscanf
__snprintf
_sprintf
_vfprintf
__vsnprintf
__assert
_vsprintf
__iob

The gnat301a examples programs are working just fine. After installing
fix2 the cal test program worked also.

my libs.ld looks like this:

SECTIONS { .text 0x401000 : {
c:\ada\win32ada\lib\win32ada.lib
C:\ADA\gnat301a\lib\libgcc.a
C:\ADA\gnat301a\lib\libada_c.a
C:\MSTOOLS\lib\user32.lib
C:\MSTOOLS\lib\kernel32.lib
}}

and winlibs.ld looks like this:

SECTIONS { .text 0x401000 : {
C:\MSTOOLS\lib\comdlg32.lib
C:\MSTOOLS\lib\advapi32.lib
C:\MSTOOLS\lib\gdi32.lib
}}

the setpath.bat for both gnat301a and win32ada are as provided and are
run in this order.

There must be a library missing. 

Waiting for more,

Jan.
