Dev - C++ - que hago mal?

al intentar realizar un programa que ejecute consultas sql:

#include <stdio.h>
#include <sql.h>
etc etc...

y al compilar me da esto:
Executing make...
make.exe -f "C:\Dev-Cpp\Makefile.win" all
gcc.exe -c compilandonideco.c -o compilandonideco.o -I"C:/Dev-Cpp/include"

In file included from C:/Dev-Cpp/include/sql.h:13,
from compilandonideco.c:3:
C:/Dev-Cpp/include/sqltypes.h:17: error: syntax error before "UDWORD"
C:/Dev-Cpp/include/sqltypes.h:18: error: syntax error before "UWORD"
C:/Dev-Cpp/include/sqltypes.h:24: error: syntax error before "PTR"
C:/Dev-Cpp/include/sqltypes.h:25: error: syntax error before "HENV"

que pasa?
