[PATCH] Fix unresolved symbols on non-C99 platforms

[Eric Botcazou]

Hi,

The patch

2005-05-18  Tobias Schl"uter  <tobias.schlueter@physik.uni-muenchen.de>

	* f95-lang.c (gfc_init_builtin_functions): Define BUILT_IN_TRUNC
	and BUILT_IN_TRUNCF instead of BUILT_IN_FLOOR and BUILT_IN_FLOORF.
	* trans-intrinsic.c (build_fix_expr): Change 'op' argument
	to correct enum type.
	(gfc_conv_intrinsic_aint): Likewise.  Clarify comment in front of
	function.  Add default case to switch, deal with FIX_TRUNC_EXPR
	instead of FIX_FLOOR_EXPR.

has broken the F95 compiler on non-C99 platforms because of the new 
dependencies on C99's 'trunc' and 'truncf'.

The attached patch adds 'trunc' and 'truncf' to intrinsics/c99_functions.c and 
tweak the configure machinery accordingly.  Built and tested on SPARC/Solaris 
2.5.1, 2.6, 7, 8, 9 (non-C99) and 10 (C99).  OK for mainline?


2005-05-20  Eric Botcazou  <ebotcazou@libertysurf.fr>

	* configure.ac: Check for trunc and truncf in libm.
	* configure: Regenerate.
	* config.h.in: Likewise.
	* intrinsics/c99_functions.c (trunc, truncf): New functions.
	* c99_protos.h (trunc, truncf): Declare them.
