[Chicken-users] autoconf build failing on posixunix.c

[john]

Hi,  I am trying to build a binary using autoconf. Everything had been
working fine until my program required the posix unit. The build now
bombs out as follows:

posixunix.c: In function 'stub355':
posixunix.c:615: error: 'C_group' undeclared (first use in this function)
posixunix.c:615: error: (Each undeclared identifier is reported only once
posixunix.c:615: error: for each function it appears in.)
posixunix.c: In function 'f_3109':
posixunix.c:10388: error: 'C_group' undeclared (first use in this function)
posixunix.c: In function 'f_3119':
posixunix.c:10404: error: 'C_group' undeclared (first use in this function)
posixunix.c: In function 'f_3127':
posixunix.c:10482: error: 'C_group' undeclared (first use in this function)
posixunix.c: In function 'f_2730':
posixunix.c:11067: error: 'C_pipefds' undeclared (first use in this function)
posixunix.c: In function 'f_2734':
posixunix.c:11081: error: 'C_pipefds' undeclared (first use in this function)
make: *** [posixunix.o] Error 1

Any pointers as what is missing from the build? I had a grep around
the source but I am lost.

TIA,

John.
