I'm currently modifying sla.c to include thread-safe "_r" variants for all the SLALIB functions (I'm just wrapping each call in a mutex lock/unlock block). I'll then look at the use of statics in smf_create_lutwcs and smf_detpos_wcs (there may be other uses of statics in smurf but these were the ones that were thrown up by the Intel thread checker). I'll then follow up Peter's suggestion about -D_REENTRANT and the use of strtok, strerror, etc. Everyone keep their fingers crossed...
