ecgpuwave program to compile

the exact version: GNU Fortran (GCC) 5.4.0

bichinda@CSC-023013 ~/ecgpuwave-1.3.3
$ make install
gfortran -std=legacy -ffixed-line-length-none -fno-automatic -g -O -Wextra -c
-o ecgpuwave.o ecgpuwave.f
      6 [main] f951 (3936) C:\cygwin\lib\gcc\i686-pc-cygwin\5.4.0\f951.exe: ***
fatal error - cygheap base mismatch detected - 0x6131F408/0x6131F400.
This problem is probably due to using incompatible versions of the cygwin DLL.
Search for cygwin1.dll using the Windows Start->Find/Search facility
and delete all but the most recent version.  The most recent version *should*
reside in x:\cygwin\bin, where 'x' is the drive on which you have
installed the cygwin distribution.  Rebooting is also suggested if you
are unable to find another cygwin DLL.

Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.
make: *** [Makefile:88: ecgpuwave.o] Error 4

the preprocessed file: I attach the complete ecgpuwave-1,3,3 archive; just
unzip and in run 'make install' in the ecgpuwave-1.3.3 filder
