When it was first included, it had a major bug in lgamma and a minor 
error in tgamma. The bug in lgamma() was fixed in the subsequent 
release. Last time I checked, tgamma was faulty (although it's subtle -- 
about the fifth digit is wrong).

I just tried to run my test program, but mathextra now gives an internal 
error (ztc.type.c 308) -- new regression in DMD 0.151, I'll track it down.
