_yy* undefined reference problem.

Good day!

I'm trying to build NCL 5.1.1 from source code. I have a WinXP SP2 machine with CygWin 1.7.1 installed on it.

I made some changes with CYGWIN config file, like changing CtoFLibraries variabl to:
#define CtoFLibraries '-L/lib/gcc/i686-pc-cygwin/3.4.4' -lg2c -lm -lrpclib

That's all changes I made.
When I try to make Everything, I get the following errors:

gcc -ansi -O -o ictrans main.o ../../../.././ncarview/src/lib/libictrans/libictrans.o ../../../.././ncarview/src/lib/libctrans/libctrans.o -L../../../.././ncarview/src/lib/libcgm -lcgm -L../../../.././ncarview/src/lib/libncarg_ras -lncarg_ras -L../../../.././common/src/libncarg_c -lncarg_c -L/usr/local/ncarg/lib -L/usr/local/lib -L/usr/X11R6/lib -lXpm -lX11 -lXext -lmfhdf -ldf -ljpeg -lz '-L/lib/gcc/i686-pc-cygwin/3.4.4' -lg2c -lm -lrpclib
../../../.././ncarview/src/lib/libictrans/libictrans.o:lex_stuff.c:(.text+0x4537): undefined reference to `_yylsp'
../../../.././ncarview/src/lib/libictrans/libictrans.o:lex_stuff.c:(.text+0x453c): undefined reference to `_yyolsp'
...
../../../.././ncarview/src/lib/libictrans/libictrans.o:lex_stuff.c:(.text+0x46b0): undefined reference to `_yyoutput'

All error messages are about _yy* stuff. I've already tried to use flex of different version (2.5.35, 2.5.3), and differnt versions of gcc compiler (4.3.4, 3.4.4). I have a g77 compiler version 3.4.4.

Hope for your fast response.
