  21  * Hasefroch compatiblity.  This header contains the rest of the junk (the
  22  * initial junk is at uftps.h) to compile the application with MinGW while
  23  * maintaining the UNIX look of the code.  Most of the wrappers are trivial, but
  24  * still was desirable to avoid having aliases for the underscore prefixed
  25  * names.
  26  *
  27  * However, the Hasefroch support is not complete.  The way WINVER is defined in
  28  * uftps.h prevents this program to be compiled or run in Hasefroch versions
  29  * prior to XP SP-1.
  30  *
  31  * NOTE: Inline functions are preferred over macros as some type checking is
  32  * allowed.  When this type checking is not appreciated, macros are used
  33  * instead.
