[NTG-context] luatex not compiling

There appears to be a problem with the compilation of luatex on MacOSX 10.5.x, but I might have found (at least one of) the cause. On my system (MacOSX10.5.1) complation halted with: luatexextra.c:408 error: storage size of 'sigstk' isn't known. Further exploring showed the cause of this: SIGSTKSZ is not defined. As it turns out SIGSTKSZ is defined in signal.h and in luatexextra.c read with #include , assuming signal.h resides in /usr/include/signal.h. That however, is not the case on this version of MacOSX: it sits in / usr/include/sys/signal.h. Probably changing the code into: #include #ifndef _SIGNAL_H_ #include #endif might help, but I have not tested this (some of the pie should be left for Taco c.s. ;-) Hans van der Meer
