From: petter_fryklund on
C_INCLUDE_PATH did not help. Changing PATH did not help. But setting
C_... and using it did ;-)
C:\GNAT\2007\bin\gcc -c -g -O2 -I%C_INCLUDE_PATH% -IC:\Tcl\include
tclmacro.c
but i was not home yet, still could not find contents of tclmacro.o =8-
O

Switches to gnatlink had to include path to tclmacro.o!
