Question about C_INCLUDE_PATH env. variable in b17.1

[gordon at oasis dot bellevue dot k12 dot wa dot us]

 I appear to be having trouble with getting the C_INCLUDE_PATH environment variable to work, whatever I set it to,
it doesn't seem to affecting the actual search paths at all.
 Here's an example:
--

D:\Cygnus>set C_INCLUDE_PATH=/cygnus/win32/include

D:\Cygnus>gcc -o hello2.exe wintest.c -lkernel32 -luser32 -Wl,--subsystem,window
s -s -v
