getpwuid_r have 5 parameters. FreeTDS seem to detect 4 parameters (see
threadsafe.c like 235). After configuring edit confih.h, define
HAVE_FUNC_GETPWUID_R_5 and undefine HAVE_FUNC_GETPWUID_R_4_PW and
HAVE_FUNC_GETPWUID_R_4. This should fix the problem...

I'll update acinclude.m4 to fix the configure problem (for 0.62).
