I updated the include files and the pcc32.exe to avoid hanging.
Download the include and pcc32.exe from: http://www.manoscoder.gr/mysite/coderstudio.htm
and replace the old.
The math.h and maybe some other require to use the: /C99 switch
in pcc32 command line, like: pcc32 /c /MD /C99 SomeFile.c
Manos.
Because the time.h has a bug, replace the old with the new one.
Manos.
