Dear Justin,

Thanks for the mail. Yes, without these CFLAGS the "make" was not
successful. Yes I did set the CPPFLAGS and LDFLAGS before configuring
gromacs. Since without it it would have stopped compiling. I want to agree
with you that it is some issue with shared libraries, but i dont think it is
the issue since I have used the flag --enable-shared. Also, if this was the
case then editconf would not have worked as well.

Thanks and Regards,
Raghu
