_ctype_ undefined?

[Mark Fitzgerald <mfitzger at elora dot math dot uwaterloo dot ca>]

I'm trying to port a game I'm writing from Borland C++ 5.01 to Cygwin
B20.1.  I've managed to work around windowsx macro problems by overwriting
cygnus' windowsx.h with Borland's (Why are so many macros missing?),
albeit with many warnings.  However, I cannot get my program to compile
without dependence on cygwin1.dll.  I try:

gcc *.o abc.coff -mno-cygwin -mwindows -lcomctl32 -lwsock32 -o abc.exe

and I get:

gcc *.o abc.coff -mno-cygwin -mwindows -lcomctl32 -lwsock32 -o abc.exe
abc.o: In function `SelectPlayersProc(void *, unsigned int, unsigned
int, long)':
/Data/Programming/cygwin/ABC_Cygwin_Port/abc.cpp:1264: undefined

/Data/Programming/cygwin/ABC_Cygwin_Port/abc.cpp:1292: undefined

abc.o:/Data/Programming/cygwin/ABC_Cygwin_Port/abc.cpp:1451: more
undefined references to `_ctype_' follow
collect2: ld returned 1 exit status
make: *** [a.exe] Error 1

Any ideas?  The lines referenced are things like:

if (!isdigit(buffer[pos++])) {
