Hello,

 configured with  gcc-2.95, hpux ld, hpux fort77, --with-readline

 I had three problems:

1. changed f77 to fort77 in Makeconf files/Makefile (I had
--with-f77=fort77 in the configure line)

2. readline : picked up that I had readline, but the include location
was inserted into the CFLAGS, and history was marked as
unavailable. Made changes to Makeconf  and etc/Makeconf 

3. LDFLAGS = -g -Wl,xx   was not acceptable to the hpux "ld" (both
have to go) Changed Makefile.

Then had a clean build.  Seems to able to load dynamic libs. 
Check fails at two locations:

is.infinite(.Machine$double.base ^ .Machine$double.max.exp)# overflow
[1] FALSE

 x <- 1:99/100
 all(abs(1 - x / asin(sin(x))) <= Meps)
[1] FALSE

Second one :
 [1]  TRUE  TRUE  TRUE  TRUE  TRUE  TRUE  TRUE  TRUE  TRUE  TRUE  TRUE  TRUE
[13]  TRUE  TRUE  TRUE  TRUE  TRUE  TRUE  TRUE  TRUE  TRUE  TRUE  TRUE  TRUE
[25]  TRUE  TRUE  TRUE  TRUE  TRUE  TRUE  TRUE  TRUE  TRUE  TRUE  TRUE  TRUE
[37]  TRUE  TRUE  TRUE  TRUE  TRUE  TRUE  TRUE  TRUE  TRUE  TRUE  TRUE  TRUE
[49]  TRUE  TRUE  TRUE  TRUE FALSE  TRUE  TRUE FALSE  TRUE  TRUE  TRUE  TRUE
[61]  TRUE  TRUE  TRUE  TRUE  TRUE  TRUE  TRUE  TRUE  TRUE  TRUE  TRUE  TRUE
[73]  TRUE  TRUE  TRUE  TRUE  TRUE  TRUE  TRUE  TRUE  TRUE  TRUE  TRUE  TRUE
[85]  TRUE  TRUE  TRUE  TRUE  TRUE  TRUE  TRUE  TRUE  TRUE  TRUE  TRUE  TRUE
[97]  TRUE  TRUE  TRUE

Flaky math routines in hpux or gcc libc.
