configure CFLAGS='-V 3.4.4' doesn't work because:
configure:3291: i686-pc-cygwin-gcc -o conftest.exe -V 3.4.4 -mno-cygwin -g co nftest.c >&5 i686-pc-cygwin-gcc: '-V' must come at the start of the command line configure:3294: $? = 1 configure:3312: error: cannot compute suffix of executables: cannot compile and link Maybe an autoconf bug. Unless gcc could loosen up its command line parsing. I'll try CC instead of CFLAGS. - Jay
