It is 3.2.3
---8<--------------------------------------------->8---
F:\MinGW\bin>gcc.exe --version
gcc.exe (GCC) 3.2.3 (mingw special 20030504-1)

I have found something in makefile:
---8<--------------------------------------------->8---
315 LOCAL_FLAGS     = -DWINDOWSNT -DDOS_NT -DSTDC_HEADERS=1 -DNO_LDAV=1 \
316                   -DNO_ARCHIVES=1 -DHAVE_CONFIG_H=1 -I../nt/inc \
317                   -I../src
---8<--------------------------------------------->8---
when run configure.bat in nt folder, I have specified '--cflags -I./inc'.
After I removed the -I../nt/inc in the makefile in lib-src folder, the  
build is OK.

It seems that only one -I flag allowed in this situation.
I specified the include path because I put all the graphic's header  
files(gif, bmp, jpg, tiff, etc) in there.

I did not know many about the flags in MinGW and GCC. Is there something  
wrong or it is the limitation of the compiler?

if removed the -I../nt/inc from makefile,
'mingw32-make movemail' make the following errors:
