No, this will not work, because I need LDFLAGS to be defined during
configuration, or configure tests will fail with something along the
line of this:

configure:15998: result: no
configure:16018: checking whether IO functions support size specifier for long 
long
configure:16045: gcc -o conftest.exe -g -O2 -I${abs_srcdir}/win32/pthread 
-DWINVER=0x0501       -D_WIN32_WINNT=0x0501 -DIN_LIBSOFIA_SIP_UA 
-DIN_LIBSOFIA_SRES   -mms-bitfields  -pipe -mno-cygwin -mwindows -mconsole 
-Wall -g -O0   -Wl,--enable-auto-image-base conftest.c 
-L${abs_srcdir}/win32/pthread -lpthreadVC2 -lws2_32        -lwsock32 >&5
c:/mingw/bin/../lib/gcc/mingw32/4.5.0/../../../../mingw32/bin/ld.exe: cannot 
find -lpthreadVC2
