[Bug inline-asm/39048] gcc 4.4.0 20090131 - Extra underscore hides libgcc's soft-fp functions from Testsuite causing FAILs + naming error in libgcc

I tossed in that patch and it cause gcc's build to fail here:

I guess that it is missing an Include file or the included files
have generated portions that missed TMODES inclusions ...


When I add these lines to the top of fixtfti.c it complains about TI_BITS:

typedef int TItype __attribute__ ((mode (TI)));
typedef unsigned int UTItype __attribute__ ((mode (TI)));

I'll play with it some more while I await the help from an expert (or
succeed in Googling my own help).


Thanks,
Rob
