[asterisk-dev] ast_expr2.c woes in trunk when cross-compiling

[Brian Capouch]

I try to keep trunk built up against the openWRT kamikaze trunk. 
Tonight, for the first time in a long time, things failed spectacularly. 
I finally got things to go, but only after an awful, awful hack.

I just built 73771; the last one that built OK for me was 68575.  I 
hadn't done any in between.

Synopsis: There appears to be a fairly recent, major rewrite of 
ast_expr2.c, found in ~/main.  This led to two problems with my 
cross-build for openWRT.

First, __USE_ISOC99 got deffed--is it supposed to be?--and that caused 
the "l" versions of all the functions to be chosen, e.g. floorl for 
FUNC_FLOOR, ceill for FUNC_CEIL, etc.  Neither my compiler nor loader 
liked that one little bit, as none of those functions are in the math lib.

So I hacked around that and #undeffed __USE_ISOC99.  But that still 
resulted in the definition of some functions that are missing in my math 
library, which caused problems--the full error output is at the end of 
the mail.

The fix?  I'm ashamed to say that completely removing the following in 
ast_expr2.c allowed me to complete the build:

FUNC_REMAINDER
FUNC_TRUNC
FUNC_LOG2
FUNC_EXP2
FUNC_ROUND

Will that lead me to tears here in a few minutes, when I fire up my 
server?  Time will tell :-)

undeffed __USE_ISOC99 ******
