looks like I've got yet another compilation problem on Leopard:

gcc -I../byterun -DCAML_NAME_SPACE -DNATIVE_CODE  -DTARGET_power -DSYS_rhapsody -O -Wall -DDARWIN_VERSION_6  -D_FILE_OFFSET_BITS=64 -D_REENTRANT  -c signals.c
In file included from signals.c:31:
signals_osdep.h: In function 'context_gpr_p':
signals_osdep.h:137: error: dereferencing pointer to incomplete type
signals_osdep.h:141: error: dereferencing pointer to incomplete type
*** Error code 1

Happens even when I try to compile 3.09 version of OCaml (on PPC, Mac OS X v.10.5.1).
Setting MACOSX_DEPLOYMENT_TARGET to 10.4 helps.

Regards,

Valentyn.
