I compiled plotutils 2.41 successfully on W2K, latest Cygwin net
release. I faced the same error message and got ridd of it by changing
the following line of <plotutils_dir>/ode/specfun.c

#ifdef NO_SYSTEM_GAMMA
#define SIGNGAM our_signgam

like this

#if defined(NO_SYSTEM_GAMMA) || defined(__CYGWIN__)
#define SIGNGAM our_signgam

Soon I faced more problems, I guess due to Cygwin's limited support for
pthreads (PTHREAD_MUTEX_INITIALIZER was undeclared).
I overcame this by installing http://sources.redhat.com/pthreads-win32/
like this:

      copy pthread.lib to /usr/local/lib/libpthread.a
      copy pthread.dll to /usr/local/bin
      rename /usr/include/pthread.h to pthread-old.h
      copy pthread.h to /usr/include

pthread.h contained the following typo:
#if !defined(_MSC_VER) && !defined(__cplusplus)
  ptw32_leanup_t *prev;

which I fixed like this:

#if !defined(_MSC_VER) && !defined(__cplusplus)
  ptw32_cleanup_t *prev;

I also had to comment out the following lines from Cygwin header files
to avoid conflicting declarations:

unistd.h:
int     _EXFUN(gethostname, (char *__name, size_t __len));

wingdi.h:
int WINAPI Escape(HDC,int,int,LPCSTR,PVOID);


However, I still haven't figured out how to compile libplotter.lib
needed for linking libplot from C++;
