No, and it never will be unless the calling convention is changed.
The mechanism used for returning float, double, and struct/union
types is not re-entrant and hence violates the pANSI standard.
Same goes for MSC. WATCOM C7.0 is the only PC/DOS C compiler
that can be considered the closest to pANSI compliant (i.e., __STDC__==1).
