[Bug c/44476] New: tclStrToD.c takes very long to compile (forever?)

[jay dot krell at cornell dot edu]

I'll probably have to debug this myself..but compiling Tcl 8.5.8's tclStrToD.c
on alphaev67-dec-osf5.1 takes an inordinately long time. I've left it running
for many minutes. Everything else in Tcl compiled fairly rapidly, just this one
file is going and going. I tried without optimizing too.
