[GRASS5] configuration/build failure on solaris 8, curses and get/putwc

[Hal Mueller]

The subject line refers to the cause of the problem, not just my 
reaction to it.  I believe the problem is nested includes from 
"curses" redefining getwc/putwc.  This is on Solaris 8 (Sparc) with 
gcc 2.8.  My results reported are from the current CVS build, but my 
results with pre4 were similar.

"configure" with the current release tree, and with pre4, fails with 
the following error:

checking for remove... yes
checking for shmat... yes
checking for IceConnectionNumber in -lICE... yes
checking for curses.h... no
configure: error: *** Unable to locate curses includes.

However, I think the problem surfaces higher up, where "configure" reports

checking how to run the C preprocessor... gcc -E
checking for ANSI C header files... yes
checking for curses.h... no
checking for limits.h... yes

The log file segment for the initial curses.h check looks like this:

configure:2319: checking for curses.h
configure:2327: gcc -E  conftest.c >/dev/null 2>conftest.out
In file included from /usr/include/curses.h:23,

/curses.h:5,
                  from configure:2323:
