Good! On some Solaris Systems, you have to use 'gmake' instead of 'make'. I wonder if you had any diffculties/warnings or if it zipped right through it.
I developed on two Sparc R220 with SunOS 5.9 on the compiler farm of cf.sourceforge.net , one would have warnings and not link using 'make'. The other one looked identical but didn't have 'make', then using 'gmake' everything went smooth without warnings.
BTW, I left a debugging message in the floating point routines in 7.3.4 in the nl-math.c module line 1411, you might want to take that out before compiling.
But now it doesn't matter as 7.3.7 is out (with unlimited size in Tcl proc: NewlispEvaluateBuffer, locale switching and consistent FP exception handling -- thanks Nigel).
